One mole of an ideal monatomic gas undergoes a reversible process described by $PV^2 = ext{constant}$. The molar heat capacity of the gas during this process is:

In which of the following processes, heat is neither absorbed nor released by a system?

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

In an isothermal process, 200 J of heat is added to a system. What is the change in internal energy of the system?

Boyle’s law holds for an ideal gas during

A lead bullet strikes against a steel plate with a velocity 200 m/s. If the impact is perfectly inelastic and the heat produced is equally shared between the bullet and the target, then the rise in temperature of the bullet is (specific heat capacity of lead = $125{\rm{Jk}}{{\rm{g}}^{ - 1}}{{\rm{K}}^{ - 1}}$)

An ideal gas at STP is contained in a thermally insulated chamber A, connected by a valve to an identical evacuated chamber B. Upon opening the valve, the gas expands into chamber B. Which thermodynamic variable remains constant during this process?

One mole of ${{\rm{O}}_2}$ gas having a volume equal to $22.4litres$ at ${0^ \circ }C$ and 1 atmospheric pressure in compressed isothermally so that its volume reduces to $11.2litres$. The work done in this process is
