For a gas C _ P - C _ V = R in a state P and C _ P - C _ V = 1 ....

For a gas CP−CV=R{C}_{\text{P}} - {C}_{\text{V}} = R in a state PP and CP−CV=1.10R{C}_{\text{P}} - {C}_{\text{V}} = 1 . 10R in a state Q,TPQ, {T}_{\text{P}} and TQ{T}_{\text{Q}} are the temperatures in two different states PP and QQ, respectively. Then

Options

  1. ATP=TQ{T}_{P} = {T}_{Q}
  2. BTP<TQ{T}_{P} < {T}_{Q}
  3. CTP=0.9TQ{T}_{P} = 0 . 9{T}_{Q}
  4. DTP>TQ{T}_{P} > {T}_{Q}

Correct answer

D. TP>TQ{T}_{P} > {T}_{Q}

Step-by-step solution

CP−CV=R{C}_{P} - {C}_{V} = R for ideal gas and gas behaves as ideal gas at high temperature, so TP>TQ{T}_{P} > {T}_{Q}.
