Chapter 24, Problem 39A

To determine

To Explain: The effect on the room temperature of kitchen if the refrigerator door is left open and the doors and windows are closed.

Explanation of Solution

Introduction:

A body is cold or hot is expressed by the term temperature. If the temperature of body is greater than the temperature of surroundings, then the body is called hot and if the temperature of body is less than the temperature of the surrounding then the body is called cold.

If the refrigerator’s door is left open while keeping the windows and doors of the kitchen closed, the temperature of the kitchen would not drop. This is because the exhaust heat of the refrigerator is in the kitchen while the cooling effect occurs inside it. So, when one puts the refrigerator’s door open then it will exhaust more heat than cooling and the kitchen will not cool.
