The adjoining figure shows graphs of pressure and volume of a gas at two temperature `T_1` and `T_2` Which of the following inferences is correct?

A

`T_1 gt T_2`

B

`T_1=T_2`

C

`T_1 lt T_2`

D

none

Text Solution

Verified by Experts

The correct Answer is:
C

`n=(P_2V)/(RT_2)=(P_1V)/(RT_1)`
`(P_2)/(T_2)=(P_1)/(T_1)`
Since `P_2 gt P_1`, hence, `T_2 gt T_1`
