The water vapour and steam are two forms of gaseous state of water. Each of them differs slightly from the other. They can be differentiated by few points explained below.
While all types of vapour are referred to as steam, not all types of vapour are considered to be steam. Water that is in its gaseous state is referred to as steam. In some situations, steam and water vapour are interchangeable terms. The term "steam" can also be used more colloquially to describe the combination of vapour and aerosol liquid water droplets suspended in the vapour.
When a material is heated to a vapourous state, steam is created. However, when a substance is kept in typical conditions, the steams that are generated are referred to as vapours.
This is explained with an example. When water is boiled, a significant quantity of steam is produced, which is extremely hot due to the energy it contains.

how to convert lbs in ton
To convert pounds (lbs) to tons, you can use the conversion factor:1 ton = 2000 lbs, This means that one ton is equivalent to 2000 pounds of weight.
The pound (lb) is a unit of weight commonly used in the United States and other countries that still use the imperial system of units. In this system, the pound is defined as a unit of force or weight, and is equivalent to 16 ounces (oz).
However, it's worth noting that the pound is not a unit of mass, which is a measure of the amount of matter in an object, but rather a unit of weight, which is the force exerted on an object due to gravity. In other words, the weight of an object can vary depending on the strength of gravity in a particular location.
To convert from pounds to tons, divide the value in pounds by the conversion factor of 2000. For example, to convert 5000 pounds to tons:
5000 lbs = 5000/2000 tons
5000 lbs = 2.5 tons
Therefore, 5000 pounds is equivalent to 2.5 tons of weight.

How to convert 97.4 f to c?
97.4°F is equivalent to 36.33°C temperature. Using formula: °C = (°F - 32) x 5/9.
A measure of something's heat or coldness is its temperature. The most often used temperature scales globally are Celsius (°C) and Fahrenheit (°F), while there are other scales as well.
To convert Fahrenheit to Celsius, you need to subtract 32 from the Fahrenheit temperature and then multiply the result by 5/9. This formula works because the freezing point of water is 32°F and 0°C, and the boiling point of water is 212°F and 100°C. So, a change of 1 degree Fahrenheit is equivalent to a change of 5/9 degree Celsius.
To convert 97.4°F to Celsius (°C), you can use the following formula:
°C = (°F - 32) x 5/9
Substituting 97.4 for °F in the formula, we get:
°C = (97.4 - 32) x 5/9 = 36.33
Therefore, 97.4°F is equivalent to 36.33°C.
It's important to note that when converting Fahrenheit to Celsius, the resulting Celsius temperature is often more precise with decimal places. In this case, the Celsius temperature is 36.33°C, which means that the temperature is between 36°C and 37°C.
To double-check your conversion, you can also use online temperature conversion tools or smartphone apps that are readily available and accurate.

our friend of mass 110 kg can just barely float in fresh water. part a calculate her approximate volume
Our friend's approximate volume is approximately 0.110 m^3.
To calculate the approximate volume of our friend, we can use the fact that she can just barely float in fresh water. This means that her weight is equal to the buoyant force acting on her. The buoyant force is given by the equation:Buoyant force = density of water x volume of displaced water x gravity
Since our friend is just barely floating, the buoyant force is equal to her weight, which is 110 kg x 9.81 m/s^2 = 1079.1 N. The density of fresh water is approximately 1000 kg/m^3.Using these values, we can rearrange the equation to solve for the volume of displaced water:
Volume of displaced water = Buoyant force / (density of water x gravity)
Volume of displaced water = 1079.1 N / (1000 kg/m^3 x 9.81 m/s^2) ≈ 0.110 m^3

What is the measure of how hard it is to stop an object in motion?
Answer:
Momentum A measure of how hard it is to stop a moving object. Related to both mass and velocity.
As part of a physics experiment, you stand on a bathroom scale in an elevator.Though your normal weight is 610N ,the scale at the moment reads 710N.IS the acceleration of the elevator upward, downward or zero? Calculate the magnitude of the elevator's acceleration. What if anything , can you say about the velocity of the elevator? Explain
The elevator could be moving upward with increasing velocity, upward with constant velocity, or even downward with decreasing velocity. We would need additional information to determine the velocity of the elevator.
What is Velocity?
Velocity is a vector quantity that describes the rate at which an object changes its position in a particular direction. It is defined as the change in position (displacement) of an object divided by the time taken to make that change. In other words, an object's velocity can change even if its speed remains the same, as long as the direction of motion changes.
The scale reads a value of 710N which is greater than the normal weight of the person (610N). This means that there must be an additional force acting on the person in the upward direction. Since the only forces acting on the person are gravity and the normal force provided by the scale, the additional force must be the force due to the upward acceleration of the elevator.
To calculate the magnitude of the elevator's acceleration, we need to use the equation:
ΣF = ma
where ΣF is the net force acting on the person, m is the mass of the person, and a is the acceleration of the elevator.
Here, the net force acting on the person is the difference between the reading on the scale (710N) and the weight of the person (610N):
ΣF = 710N - 610N = 100N
The mass of the person can be calculated using the formula:
m = F/g
where F is the weight of the person and g is the acceleration due to gravity (approximately 9.81 m/s²):
m = 610N / 9.81 m/s² = 62.2 kg
Now, we can use the equation ΣF = ma to calculate the acceleration of the elevator:
100N = 62.2 kg x a
a = 1.61 m/s²
Therefore, the magnitude of the elevator's acceleration is 1.61 m/s² upward.
Regarding the velocity of the elevator, we cannot say anything with certainty based on this information alone. The elevator could be moving upward with increasing velocity, upward with constant velocity, or even downward with decreasing velocity. We would need additional information to determine the velocity of the elevator.

There is some friction present; the kinetic coefficient of friction is 6.00x10^-2. Since you can't walk up the incline, you give the box a push that gives it an initial velocity; then the box slides up the incline, slowing down under the forces of friction and gravity. Take acceleration due to gravity to be 9.81 m/s^2Hint 1. How to approach the problem Hint 2. Find the total work done on the box Hint 3. Initial kinetic energy Hint 4. What is the final kinetic energy?
Answer:
Wtotal = KEfinal - KEinitial
42.81 J + 1.47 N * u^2 * 1.70 m/kg
Explanation:
To solve this problem, we can use the work-energy principle, which states that the net work done on an object is equal to its change in kinetic energy. We can break the problem down into several steps to determine the total work done on the box and its final kinetic energy.
Step 1: Find the work done by gravity
The gravitational force acting on the box as it moves up the incline is given by Fg = mgsin(theta), where m is the mass of the box, g is the acceleration due to gravity, and theta is the angle of the incline. The work done by gravity over a vertical distance h is given by Wg = Fg*h. Plugging in the values given in the problem, we get:
Fg = 2.50 kg * 9.81 m/s^2 * sin(30.0°) = 12.23 N
Wg = Fg * 3.50 m = 42.81 J
Step 2: Find the work done by friction
The frictional force acting on the box is given by Ff = mgcos(theta)mu, where mu is the kinetic coefficient of friction. The work done by friction over a horizontal distance s is given by Wf = Ffs. Since the box starts from rest and comes to a stop, the work done by friction must be equal to the initial kinetic energy of the box. Plugging in the values given in the problem, we get:
Ff = 2.50 kg * 9.81 m/s^2 * cos(30.0°) * 6.00x10^-2 = 1.47 N
Wf = Ff * s
To find the distance s, we can use the fact that the box comes to a stop at the highest point of its trajectory, where its final velocity is zero. Using the equations of motion, we can find the distance s:
v^2 - u^2 = 2as
where v is the final velocity (0 m/s), u is the initial velocity, a is the acceleration (given by Ff/m), and s is the distance traveled.
Plugging in the values given in the problem, we get:
0 - u^2 = 2 * (1.47 N) / 2.50 kg * s
s = u^2 / (2 * (1.47 N) / 2.50 kg) = u^2 * 1.70 m/kg
Step 3: Find the total work done on the box
The total work done on the box is the sum of the work done by gravity and the work done by friction:
Wtotal = Wg + Wf = 42.81 J + Ff * s
Plugging in the values of Ff and s, we get:
Wtotal = 42.81 J + 1.47 N * u^2 * 1.70 m/kg
Step 4: Find the initial kinetic energy and final kinetic energy
The initial kinetic energy of the box is given by KE = 1/2 * m * u^2, where m is the mass of the box and u is the initial velocity. The final kinetic energy of the box is zero, since it comes to a stop at the highest point of its trajectory.
Therefore, the initial kinetic energy is:
KE = 1/2 * 2.50 kg * u^2
And the final kinetic energy is:
KE = 0 J
Putting it all together, we get:
Wtotal = KEfinal - KEinitial
42.81 J + 1.47 N * u^2 * 1.70 m/kg
for a pair of objects, the center of mass is located_________
For a pair of objects, the center of mass is located at a point between the two objects where the total mass of the system is concentrated.
The center of mass is the average position of all the particles in the system, weighted by their respective masses.
The location of the center of mass depends on the relative masses and positions of the objects in the system. For example, if two objects have equal masses and are located at the same distance from each other, the center of mass will be located at the midpoint between them. However, if the objects have different masses or are located at different distances from each other, the center of mass will be located closer to the more massive or more distant object.
The concept of center of mass is important in many areas of physics, including mechanics, astronomy, and fluid dynamics. It is used to describe the motion of systems of particles, such as planets orbiting around a star or a projectile moving through the air.
