Thermodynamic Processes

During an experiment, an ideal gas is found to obey an additional law VP2=VP^{2} = constant. The gas is initially at temperature ' T ' and volume ' V '. What will be the temperature of the gas when it expands to a volume 2 V?

Show answer and solution

Answer: (c)

  1. VP2=VP^2 = constant ⇒P∝V−1/2\Rightarrow P \propto V^{-1/2}.
  2. T∝PV∝V1/2T \propto PV \propto V^{1/2}
  3. V→2VV \to 2V: T′=2 TT' = \sqrt{2}\,T, so the answer is (c).
