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.
