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.
Answer:
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.
