An ideal gas follows a process described by the equation PV ^2= C from the initial ( P ₁, ~V ₁, ~T ₁ ) to final ( . P ₂, ~V ₂, ~T ₂ ) thermodynamic states, where C is a constant. Then:
Options
- AIf P ₁> ₂ then T ₁ < T ₂
- BIf V ₂> V ₁ then T ₂> T ₁
- CIf V ₂> V ₁ then T ₂ < T ₁
- DIf P ₁> P ₂ then V ₁> V ₂
Correct answer
C. If V ₂> V ₁ then T ₂ < T ₁
Step-by-step solution
As per question, PV ^2= C And by ideal gas equation, we have; PV =n RT Hence, ( n RT V ) V ^2= C Hence, TV = constant T 1 ~V V ₂ > V ₁ and T ₁ > T ₂
