The pressure and volume of a gas are changed as shown in the p-V diagram in the figrue ahead. The thmperature of the gas

A

increases as if goes from A to B

B

Increases as it goes from B to C

C

Remains constant during these changes

D

Decreases as it goes from D to A

Once again plot the rectangular cycle aginst the beckground of various dotted isothermal lines.

Note here `T_8 gt T_7 gt T_6 gt T_5 gt … gt T_1`. So, in the process D to A the temperature increases. In A to B it further increases. In B to C it decreases and in C to D it decreases. So, the correct respone is (1).
