NEET Physics Thermodynamics Questions Solved

NEET - 2012

 

One mole of an ideal gas from an initial state B undergoes via two processes. It first undergoes isothermal expansion from volume V to 3V and then its volume is reduced from 3V to V at constant pressure. The correct p-V diagram representing the two processes is -

 

According to question first gas goes from volume V to 3V and after this volume is reduced from 3V to V at constant pressure. In isothermal expansion p-V curve is rectangular hyperbola.
