2001B6. A cylinder is fitted with a freely moveable piston of area `1.20×10−2m2` and negligible mass. The cylinder below the piston is filled with a gas. At state 1 , the gas has volume `1.50×10−3m3`, pressure `1.02×105Pa`, 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.
