Chapter 6.2, Problem 6.2CC

Interpretation Introduction

Interpretation:

The change in internal energy of the system has to be calculated.

Concept introduction:

First law of thermodynamics:

The change in internal energy of a system is equals to heat plus work.

$\begin{array}{l}\text{ΔU}\text{=}\text{q}\text{+}\text{w}\\ \text{where,}\\ \text{ΔU}\text{-}\text{internal}\text{energy}\text{change}\\ \text{q}\text{-}\text{heat and}\text{w}\text{-}\text{work}\text{.}\end{array}$
