Sams laptop will be cooler than Odessas laptop, because less energy has to transfer for the molecules of Sams laptop to reach the same temperature as the molecules of Aruns laptop.b. Both laptops will be the same temperature, because both Aruns and Maris laptops had the same amount of energy to transfer and the molecules in Sams and Odessas laptops started with the same energy.c. Odessas laptop will be cooler than Sams laptop, because Odessas started with more total energy, so less energy has to transfer for her and Aruns laptops to reach the same total energy.d. Odessas laptop will be cooler than Sams laptop, because the energy that transferred to Odessas was spread out over more molecules.
