A volume `V` absolute temperature `T` diagram was obtained when a given mass of gas was heated. During the heating process from state `1` to `2`, the pressure

A

remained same

B

decreased

C

increased

D

none

Text Solution

Verified by Experts

The correct Answer is:
B

`tantheta=(V)/(T)=(nR)/(P)`
`1rarr2`, `theta` is increasing i.e., P is decreasing.
