A Cylinder Contains 8 $5.3 \times 10 ^ { 5 } \mathrm {~Pa}$

question 16

Short Answer

A cylinder contains 8.8 moles of ideal gas, initially at a temperature of 126°C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of $5.3 \times 10 ^ { 5 } \mathrm {~Pa}$ on the gas. The gas is cooled until its temperature has decreased to $27 ^ { \circ } \mathrm { C }$ For the gas $\mathrm { C } _ { \mathrm { V } } = 13.73 \mathrm {~J} / \mathrm { mol } \cdot \mathrm { K }$ The ideal gas constant is R = 8.314 J/mol ∙ K. For this process, calculate:
(a) the work done by gas
(b) the net change in the internal (thermal) energy of the gas
(c) the heat transferred to the gas.
