below the piston is filled with a gas. At state 1, the gas has volume 1.50 x 10-3 m³, pressure 1.02 x 10^5 Pa
and the cylinder is in contact with a water bath at a temperature of 0°C. The gas is then taken through the
following four-step process.
A 2.50 kg metal block is placed on top of the piston, compressing the gas to state 2, with the gas
still at 0°C.
• The cylinder is then brought in contact with a boiling water bath, raising the gas temperature to
100°C at state 3.
.The metal block is removed and the gas expands to state 4 still at 100°C.
Finally, the cylinder is again placed in contact with the water bath at 0°C, returning the system to
state 1
(a) Determine the pressure of the gas in state 2.
(b) Determine the volume of the gas in state 2.
(c) Indicate below whether the process from state 2 to state 3 is isothermal, isobaric, or adiabatic.
_______Isothermal _______Isobaric Adiabatic
Explain your reasoning.
(d) Is the process from state 4 to state 1 isobaric? ___YES ___NO
Explain your reasoning.
(e) Determine the volume of the gas in state 4.
