The substances in the table are combined, and substance 1 loses 40 calories of heat. how many calories of heat will substance 2 eventually gain? a) 0 b) 20 c) 40 d) 80

Over time, the substances will reach equilibrium, meaning the heat calories lost by Substance 1 will be gained by Substance 2. Therefore, Substance 2 will eventually gain 40 calories of heat.

C) 40

Explanation:

When any two substances having different thermal energy are combined, one loses the energy and other gains till the two are in thermal equilibrium. Thus, the substance 1 loses 40 calories which would be gained by substance 2. The two will be in thermal equilibrium.

Thus, substance 2 would gain 40 calories.
