One mole of an ideal gas goes from an initial state AA to final state BB via two processes. It first undergoes isothermal expansion from volume VV to 3V3 V and then its volume is reduced from 3V3 V to VV at constant pressure. The correct p−Vp-V diagram representing the two processes isOne mole of an ideal gas goes from an initial state A to final state B via two processes.

Options

  1. AA voltmeter of resistance 20000 reads 5 volt. To make it read 20 volt, the extra resistance required is
  2. BA voltmeter of resistance 20000 reads 5 volt. To make it read 20 volt, the extra resistance required is
  3. CA voltmeter of resistance 20000 reads 5 volt. To make it read 20 volt, the extra resistance required is
  4. DA voltmeter of resistance 20000 reads 5 volt. To make it read 20 volt, the extra resistance required is

Correct answer

D. A voltmeter of resistance 20000 reads 5 volt. To make it read 20 volt, the extra resistance required is

Step-by-step solution

According to question first gas goes from volume VV to 3V3 V and after this volume is reduced from 3V3 V to VV at constant pressure. In isothermal expansion p−Vp-V curve is rectangular hyperbola. Option (4) is correct
