Medium MCQ +4 / -1 PYQ · JEE Mains 2021

For a gas CP $-$ CV = R in a state P and CP $-$ CV = 1.10 R in a state Q, TP and TQ are the temperatures in two different states P and Q respectively. Then

  1. A T<sub>P</sub> = T<sub>Q</sub>
  2. B T<sub>P</sub> &lt; T<sub>Q</sub>
  3. C T<sub>P</sub> = 0.9 T<sub>Q</sub>
  4. D T<sub>P</sub> &gt; T<sub>Q</sub> Correct answer

Solution

C<sub>P</sub> $-$ C<sub>V</sub> = R for ideal gas and gas behaves as ideal gas at high temperature, so T<sub>P</sub> &gt; T<sub>Q</sub>
