Textbook Problem

A gas is compressed inside a cylinder (Figure 5.16), An average force of 50 N acts to move the piston 0.1 m. During the compression, 2 J of heat are conducted away from the gas. What is the change in internal energy of the gas?

To determine

The change in internal energy of the gas.

Explanation

Given info:

Average force acting on the piston, F=50 N

Displacement in the piston due to the force, s=0.1 m

Heat conducted away from the system, Q=2 J, (negative sign since heat is taken away from the gas).

Formula used:

First Law of Thermodynamics is used which states the change in internal energy of a substance equals the work done on it plus the heat transferred to it. Mathematically

ΔU=work+Q
