a gas cylinder in the lab contains 12.0 ft3 of some gas at 70ºF and 100psia. The gas is then compressed to 2.0 ft 3 in an experiment. Assuming isothermal conditions, and using the ideal gas law, what is the pressure of the new volume?
Homework Answers
Answer:
At isothermal condition, temperature remains constant.
Then pressure is inversely proportional to volume (Boyels law)
PV=constant or P1V1=P2V2
Given P1=100 psia, V1=12 ft3 and V2=2 ft3 then P2=?
Therefore P2=P1V1/V2=(100 psia x 12 ft3)/(2 ft3)
P2=600 psia.
Therefore the pressure of the new volume=600 psia.

An ideal gas is contained in a cylinder equipped with a frictionless, nonleaking piston of area A. When the pressure is atmospheric P0, the piston face is at a distance l from from the closed end. The gas is compressed by moving the piston a distance x. Calculate the spring constant, or force constant, F/x, under (a) isothermal conditions and (b) under adiabatic conditions. (c) In what respect is a gas cushion superior to a steel spring?

To practice Problem-Solving Strategy 19.1 Work in Ideal-gas Processes. A cylinder with initial volume V contains a sample of a gas at pressure p. On one end of the cylinder, a piston is let free to move so that the gas slowly expands in such a way that its pressure is directly proportional to its volume. After the gas reaches the volume 3V and pressure 3p, the piston is pushed in so that the gas is compressed isobarically to its...
