Question

1. A metal cylinder has a base area of A= 0.01 m² and is fitted with a piston that can freely move. The cylinder is filled with n=0.055 mol of an ideal gas that has pressure P? = 104,000 Pa, a volume V? = 0.0012 m³, and a temperature of T? = 0 ° C when in State 1. The gas is then taken through the four-step process below: State 1 T? = 0 °C State 2 T? = 0 °C State 3 T? = 100 °C State 4 T? = 100 °C A Piston Gas Ice Water Ice Water Boiling Water Boiling Water 1 ? 2: A metal block of mass m = 42 kg is placed on top of the piston of area "A", compressing the gas to State 2 while in contact with an ice-water bath, keeping the gas at T? = 0 ° C. 2 ? 3: With the block still on the piston, the ice water bath is then removed and instead a boiling water bath is put in contact with the cylinder, raising the gas temperature to T? = 100 ° C in State 3. 3 ? 4: The block is then removed from the piston, and the gas expands to State 4 while still in contact with the boiling water bath, keeping the gas at T? = 100 ° C. 4 ? 1: Finally, the boiling water bath is removed and replaced by the ice-water bath, and the gas temperature is brought back down to T? = 0 ° C in State 1. (a) For each process below, circle one process type: The process from State 1 to State 2: isothermal isobaric isovolumetric adiabatic The process from State 2 to State 3: isothermal isobaric isovolumetric adiabatic The process from State 3 to State 4: isothermal isobaric isovolumetric adiabatic The process from State 4 to State 1: isothermal isobaric isovolumetric adiabatic

is filled with n=0.055 mol of an ideal gas that has pressure P? = 104,000 Pa, a volume V? = 0.0012 m³, and a

1 ? 2: A metal block of mass m = 42 kg is placed on top of the piston of area "A", compressing the gas to
State 2 while in contact with an ice-water bath, keeping the gas at T? = 0 ° C.
2 ? 3: With the block still on the piston, the ice water bath is then removed and instead a boiling water
bath is put in contact with the cylinder, raising the gas temperature to T? = 100 ° C in State 3.
3 ? 4: The block is then removed from the piston, and the gas expands to State 4 while still in contact with
the boiling water bath, keeping the gas at T? = 100 ° C.
4 ? 1: Finally, the boiling water bath is removed and replaced by the ice-water bath, and the gas
temperature is brought back down to T? = 0 ° C in State 1.
(a) For each process below, circle one process type:
The process from State 1 to State 2: isothermal isobaric isovolumetric adiabatic
The process from State 2 to State 3: isothermal isobaric isovolumetric adiabatic
The process from State 3 to State 4: isothermal isobaric isovolumetric adiabatic
The process from State 4 to State 1: isothermal isobaric isovolumetric adiabatic
