A monoatomic ideal gas undergoes a process in which the ratio of

P

V

at any instant is constant and equal to unity. The molar heat capacity of the gas is

View answer and explanation

Correct option: A

\frac{{4R}}{2}

Option A (4R/2) is correct because the molar heat capacity is calculated using the given condition P/V = 1 and the ideal gas law.
