First Law of Thermodynamics — Prelims Questions

A gas is compressed adiabatically. Which of the following statements is true regarding this process?

An ideal gas undergoes a cyclic process ABCA as shown in the P-V diagram. The work done by the gas during the cycle is:

A system absorbs $200,\text{J}$ of heat and performs $150,\text{J}$ of work. What is the change in the internal energy of the system?

For an ideal gas, which of the following processes results in zero change in internal energy?

One mole of an ideal monatomic gas ($C_V = \frac{3}{2}R$) is heated at constant volume from $27^circ\text{C}$ to $127^circ\text{C}$. The heat absorbed by the gas is:

An ideal gas expands from volume $V_1$ to $V_2$ in three different processes: (i) Isothermal, (ii) Adiabatic, (iii) Isobaric. If the initial and final volumes are the same for all processes, and the initial pressure is the same, which process does the most work?
