Chapter 12, Problem 42A

To determine

When thermal energy is transferred from a warmer object to a colder object, whether the two have the same temperature changes.

Explanation of Solution

Introduction:

When thermal energy is transferred from a warmer object to a colder object, the change in temperature depends upon the specific heat capacities of the object.

When two bodies are in contact, heat flows from the hotter body to colder body. Equal amounts of energy is lost and gained. But the temperature change is not necessarily the same as it is dependent on the specific heat capacity of the two bodies.

Conclusion:

When thermal energy is transferred from a warmer object to a colder object, the two do not have the same temperature changes.
