Question

Figure shows graphs of pressure versus density for an ideal gas at two temperatures `T_(1)` and `T_(2)` Which is correct ?
.
A. `T_(1)gt T_(2)`
B. `T_(1)= T_(2)`
C. `T_(1) lt T_(2)`
D. None of these

Answer 1

Correct Answer - A
as, `pV =nRTm/MTR`
ehere, M= molecular weight
`rArr" "p/(m//V)=(RT)/M rArrp/p=(RT)/MrArrp/ppropT`
`" "`(`therefore` for a given gas M is constants) ltbtgt Temperature is directly proportional to the slope of p-p graph. So, `T_(1)gtT_(2^.)`
