Question

(II) A gas is enclosed in a cylinder fitted with a light frictionless piston and maintained at atmospheric pressure. When 254 kcal of heat is added to the gas, the volume is observed to increase slowly from 12.0 m$^3$ to 16.2 m$^3$. Calculate ($a$) the work done by the gas and ($b$) the change in internal energy of the gas.

Step 1

Given: Initial volume, $V_1 = 12.0 m^3$ Final volume, $V_2 = 16.2 m^3$ Pressure, $P = \text{atmospheric pressure}$ Change in volume, $\Delta V = V_2 - V_1 = 16.2 m^3 - 12.0 m^3 = 4.2 m^3$ Work done by the gas can be calculated using the formula: $W = P \cdot Show more…
