Question

How much work is done blowing up an empty bag to a volume of 0.03 cubic meters in a constant pressure environment of 1 atmosph

Answer 1

The work done on the gas is 3039 J

Explanation:

The work done to expand of compress a gas at constant pressure is given by

$W=p\Delta V$

where

p is the pressure of the gas

$\Delta V = V_f - V_i$ is the change in volume of the gas, where

$V_f$ is the final volume

$V_i$ is the initial volume

In this problem we have:

$\Delta V=0.03 m^3$ (change in volume of the gas)

$p=1 atm = 1.013\cdot 10^5 Pa$ is the pressure of the gas

Substituting,

$W=(1.013\cdot 10^5)(0.03)=3039 J$
