Question

An ideal gas and a block of copper, have equal volumes of 0.5 m3 at 300 K and atmospheric pressure. The pressure on both is increased reversibly and isothermally to 5 atm.
a. Explain with the aid of a P-V why the work is not the same in the two processes.
b. In which process is the work done greater?
c. Find the work done on each if the compressibility of the copper is 161070???atm..
d. Calculate the change in volume in each case.

Explanation / Answer

Because work equals forse multipled by the displacement. The gas will displace more than the copper => the force will do more work when applied to the gas. (shortly - gas will contract and change its energy, copper will not)
