Chapter 2, Problem 2.9P
Interpretation Introduction

Interpretation:

The amount of energy transferred as work in the given closed system and for a process causing the same change of state but for which the work is zero, how much heat is transferred.

Concept introduction:

First Law of Thermodynamics states that the energy can transfer from one form to another form but neither be created nor be destroyed. Thus, in an isolated system, total energy is constant.

The mathematical expression is given by:

  ΔU=Q+W

Where,

△U is change in internal energy
Q is heat
W is work done

Closed system is defined as the system in which there is no exchange of energy or mass inside or outside the system.
