A 10.0 cm radius piston compresses a gas isothermally from a height of 15.0 cm to 2.50 cm at a constant pressure of 2.0 atm.
Sketch a PV diagram for the following process:
A 2.0 L gas undergoes an isovolumetric increase in pressure from 1.0 atm to 2.0 atm
An isothermal compression from 2.0 atm and 2.0 L to 1.0 atm and 1.0 L
An isobaric compression from 2.0 L to 1.0 L
An ideal gas expands at a constant total pressure of 2.5 atm
from 3.45 L to 6.70 L. Heat then flows out of the gas at constant
volume, and the pressure and temperature are allowed to drop until the
temperature reaches its original value. Calculate:
the total work done by the gas in the process
the total heat flow into the gas.
Heat flows into an ideal gas at a constant volume. The pressure
increases from 1.5 atm to 5.5 atm. Next the gas is compressed at
constant pressure from 5.0 L to 2.5 L and goes back to its original
What is the total work done on the gas in the process?
