Question

Substance A has a heat capacity that is much greater than that of substance B. If 10.0 g of substance A initially at 30.0 ∘C is brought into thermal contact with 10.0 g of B initially at 80.0 ∘C, what can you conclude about the final temperature of the two substances once the exchange of heat between the substances is complete?

Answer 1

Explanation:

In a heat exchange, the temperature change is inversely proportional to the specific heat capacity. Since substance A has a heat capacity that is much greater than that of substance B, the temperature change of substance A will be less than the temperature change of substance B. Therefore, the final temperature is closer to that of $30^\circ C$ than $80^\circ C$.
