Chapter 5, Problem 9STP

To determine

To define the term heat and state its unit.

Answer to Problem 9STP

Heat is defined as an energy which transfers between two objects and measured in joule.

Explanation of Solution

Introduction:

Heat is an energy which transforms directly into the kinetic energy. Heat energy transfers from one body to other body due to temperature difference.

Heat flows from high temperature region to low temperature region. The temperature of the substance increases when it absorbs the heat. It describe the degree of hotness of the body. Heat can be converted into various forms. It is measured in joule or calorie.

Conclusion:

Hence, the heat is a form of energy that measured in joule.
