Given below are two statements
Statement-I: When μ moles of ideal diatomic gas undergoes adiabatic change from state $(P_{1}, V_{1}, T_{1})$ to state $(P_{2}, V_{2}, T_{2})$ , such that pressure decreases then work done is positive
Statement-II: In an adiabatic process, when work is done on the gas, the temperature of the gas decreases. Choose the correct answer from the options given below

Detailed Solution

Solution: (3)
When pressure decreases, in an adiabatic process, volume increases as PV^γ is constant. Then work done is positive due to expansion of gas
We know that ΔW=-ΔU , when work is done on the gas, the temperature of the gas increases as work done is negative
