Acompression at a constant pressure of 200 kpa is performed on 8.00 moles of an ideal monatomic gas. the compression reduces the volume of the gas from 0.200 cubic meters to 0.120 cubic meters. develop a strategy to determine the amount of work that was done by the gas during this process?

In an isobaric process (constant presure), the work done by a gas is given by

where
p is the gas pressure
is the final volume of the gas
is the initial volume of the gas

In this problem:



Therefore, the work done by the gas is

and the negative sign means the work is done by the environment on the gas.

Nps pollution is caused by rainfall or snowmelt moving over and through the ground. nonpoint source pollution can include: excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. oil, grease and toxic chemicals from urban runoff and energy production
