One mole of an ideal gas at an initial temperature of ' T ' K does ' 6 R ' of work adiabatically. If the ratio of specific heats of this gas at constant pressure and at constant volume is 5 / 3 , the final temperature of gas will be ( . R =8.31 ~J ~mole ⁻¹ ~K ⁻¹ )

Options

  1. A(T+4 2) K
  2. B( T -4 2) K
  3. C(T+4) K
  4. D(T-4) K

Correct answer

D. (T-4) K

Step-by-step solution

For an adiabatic process, W = nR ( ~T _ i - T _ f ) -1 array ll & 6 R= R (T-T_f ) ( 5 3 -1 ) . (Given: n =1) & T_f=(T-4) K array
