Question

moles of an ideal monoatomic gas is expanded according to relation PT = constant from its initial state ( P 0 ​ V 0 ​ ) to the final state, due to which its pressure becomes half of the initial pressure. The change in internal energy is

TestHub · Accepted Answer

PT = const: when P → P 0 ​ /2 , T → 2 T 0 ​ . Δ U = n C V ​ Δ T = 2 × 2 3 R ​ × T 0 ​ = 3 R T 0 ​ = 2 3 ​ P 0 ​ V 0 ​ ( using P 0 ​ V 0 ​ = 2 R T 0 ​ ) .
