Question
Chapter 9, Problem 3E
Interpretation Introduction
Interpretation:
Heat and work are to be explained on the basis of molecular point of view.
Concept introduction:
Heat is the energy which is transferred between two objects when they have a difference of temperature. If the temperature between the cold object and the hot object is larger, the flow of heat will also be larger.
