Question
The gas does positive work on Its surroundings. The surroundings do positive work on the gas. Gas in a container is at a pressure of 1.7 atm and a volume of 1.0 m^3. What Is the work done on the gas If It expands at constant pressure to twice Its Initial volume? Use the expression relating the pressure and change In volume to the work done. J What is the work done on the gas if it Is compressed at constant pressure to one-quarter of its Initial volume? Use the expression relating the pressure and change in volume to the work done J One mole of an ideal gas initially of a temperature of T, Calculate the new temperature T of the gasExplanation / Answer
work done = pressure * change in volume
pressure = 1.7 atm or 172252 Pa
work done by the gas = 172252 * (2 - 1)
work done on the gas = -172252 J
in second scenario
work done by the gas = 172252 * (1/4 - 1)
work done on the gas = 129189 J
