When 1 mole of an ideal monoatomic gas is compressed adiabatically the internal energy change involved is 24 cals. The temperature rise(in kelvin) is

Correct answer

8

Step-by-step solution

⇒ Δ U=nC v Δ T ⇒ 24 = 1 × 3 2 R × Δ T ∴   for   mono atomic gas   C v = 3 2 R ⇒ Δ T = 24 × 2 3 × 2 = 8   K
