On Sam’s laptop, and Arun puts his laptop on Odessa’s laptop. The diagram above shows the laptops before they touch each other. Use the information in the diagram to answer the question.
After the laptops have been touching for a while, will Sam’s laptop or Odessa’s laptop be cooler, and why?


a. Sam’s laptop will be cooler than Odessa’s laptop, because less energy has to transfer for the molecules of Sam’s laptop to reach the same temperature as the molecules of Arun’s laptop.


b. Both laptops will be the same temperature, because both Arun’s and Mari’s laptops had the same amount of energy to transfer and the molecules in Sam’s and Odessa’s laptops started with the same energy.

c. Odessa’s laptop will be cooler than Sam’s laptop, because Odessa’s started with more total energy, so less energy has to transfer for her and Arun’s laptops to reach the same total energy.


d. Odessa’s laptop will be cooler than Sam’s laptop, because the energy that transferred to Odessa’s was spread out over more molecules.

Use the scenario below to answer the following question

Jerimiah and Nicko were discussing how well a vehicle uses its energy. They add a gallon of gasoline to the vehicle and observe the vehicle as their friend drives it in a circle around them. Jerimiah and Nicko hear the sound of the running engine, feel heat coming off of the exhaust and off the engine, and can see the vehicle move around them. After doing calculations they realize the vehicle did not travel nearly as far as they thought it would when it used the gallon of gasoline. Jerimiah claims that the energy must have been destroyed during its use, which is why they both heard the engine noises and felt the heat coming off. Nicko claims that the energy could not have been destroyed, but cannot determine what happened to all of the energy.

What can Nicko say that will explain why the energy was not destroyed during their test?
