10 moles of an ideal gas is confined in a piston-cylinder device. The gas is initially at T = 300 K and P = 1 bar. It is compressed isothermally to 10 bar. The gas has a heat capacity CV = (5/2)R.
A) What is the final volume of the gas?
B) How much work is required to accomplish the compression?
C) What is the change in internal energy of the ideal gas?
D) What is the change in enthalpy of the ideal gas?
Here temperature is constant. Change in internal energy is 0.
dH ?= C_P dT for any ideal gas process, whether constant pressure or not.
Here temperature is constant. Change in enthalpy is 0.
