Q1medium

An ideal gas undergoes an isothermal expansion from volume V1V_1 to V2V_2. If the initial pressure is P1P_1 and the final pressure is P2P_2, what is the work done by the gas?

Q2medium

A monatomic ideal gas at 27C27^\circ\text{C} is suddenly compressed to one-eighth of its original volume. If γ=5/3\gamma = 5/3, what is the final temperature of the gas?

Q3easy

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

Q4easy

In a cyclic process, an ideal gas absorbs 200J200\,\text{J} of heat from a hot reservoir and rejects 150J150\,\text{J} of heat to a cold reservoir. What is the net work done by the gas in one cycle?

Q5easy

A gas expands from 1L1\,\text{L} to 3L3\,\text{L} against a constant external pressure of 1atm1\,\text{atm}. If 1Latm=101.3J1\,\text{L}\cdot\text{atm} = 101.3\,\text{J}, what is the work done by the gas?

Q6medium

An ideal gas is taken through a cycle A \to B \to C \to A as shown in the P-V diagram. If the work done during A \to B is 100J100\,\text{J}, during B \to C is 50J50\,\text{J}, and during C \to A is 20J-20\,\text{J}, what is the net heat absorbed by the gas during the entire cycle?
