Question

A pressure P, absolute temperature T, graph was obtained whe a given mass of a gas heated. During the heating process from the state 1 to the state 2, the volume
A. remained same
B. decreased
C. increased
D. none

Answer 1

Correct Answer - C

Slope : `tantheta_1=((P)/(T))_1=(nR)/(V_1)`
`tantheta_2=((P)/(T))_2=(nR)/(V_2)`
`tantheta_1 gt tantheta_2`
`(nR)/(V_1) gt (nR)/(V_2)`
`V_2 gt V_1`
`1rarr2` volume is increasing
