Problem 12: There is an increase of internal energy by 400 joules when 800 joules of work is done by a system. What is the amount of heat is supplied during the process?

Solution:

Step: 1 Overview

From the overview of problem 3, we know that:
ΔQ=ΔU+W

Step: 2 Calculation

Given:
ΔU=400J
W=800J
Solution:
ΔQ=ΔU+W
ΔQ=400J+800J
ΔQ=1200J (Ans)
