Argon and oxygen are both compressed adiabatically from the same initial pressure and volume `(P_1, V_1)` to same final pressure `P_2` and volume `V_2`. The work done will be
| A. |
same in both cases |
| B. |
More for Argon |
| C. |
More for oxygen |
 |
| D. |
May be Ar or `O_2` depending upon their initial temperature |
