The volume of 1 mole of an ideal gas with the adiabatic exponent ` gamma ` is changed accoring to the relation ` V =( b ) /(T) ` where b= constant . The amount of heat absorbed by the gas in the process if the temperature is increased by ` Delta T ` will be

Options

A. `(( 1- gamma )/( gamma +1))R Delta T `
B. ` (R )/( gamma - 1) Delta T `
C. `((2-gamma )/( gamma -1))R Delta T `
D. `(R Delta T)/( gamma -1) `
