Thermodynamic Processes — MCQ Practice

An ideal gas undergoes an isothermal expansion from volume $V_1$ to $V_2$. If the initial pressure is $P_1$ and the final pressure is $P_2$, what is the work done by the gas?

A monatomic ideal gas at $27^circ\text{C}$ is suddenly compressed to one-eighth of its original volume. If $gamma = 5/3$, what is the final temperature of the gas?

Which of the following statements is true for an isochoric process involving an ideal gas?

In a cyclic process, an ideal gas absorbs $200,\text{J}$ of heat from a hot reservoir and rejects $150,\text{J}$ of heat to a cold reservoir. What is the net work done by the gas in one cycle?

A gas expands from $1,\text{L}$ to $3,\text{L}$ against a constant external pressure of $1,\text{atm}$. If $1,\text{L}cdot\text{atm} = 101.3,\text{J}$, what is the work done by the gas?

An ideal gas is taken through a cycle A $o$ B $o$ C $o$ A as shown in the P-V diagram. If the work done during A $o$ B is $100,\text{J}$, during B $o$ C is $50,\text{J}$, and during C $o$ A is $-20,\text{J}$, what is the net heat absorbed by the gas during the entire cycle?
