8. a gas is contained in a horizontal piston-cylinder apparatus at a pressure of 350 kpa and a volume of 0.02 m3 . determine the work done by the piston on the gas if the cylinder volume is increased to 0.15 m3 through heating. assume the pressure of the

45500 J

Explanation:

Pressure, P =350 kPa = 350 x 1000 Pa

V1 = 0.02 m^3

V2 = 0.15 m^3

Work done by the piston

W = Pressure x increase in volume

W = P x (V2 - V1)

W = 350 x 1000 (0.15 - 0.02)

W = 45500 J

Thus, the work done is 45500 J.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
