Question

Figure shows the volume versus temperature graph for the same mass of a gas (assumed ideal) corresponding to two different pressure `P_(1) and P_(2)`. Then

A. `P_(1) gt P_(2)`
B. `P_(1) lt P_(2)`
C. `P_(1) = P_(2)`
D. The information is insufficient

Answer 1

Correct Answer - A
Since the graph is a straight line.
so, `V = mT` where `m` is the slope,
`=(nRT)//P` [from equation of state]
or `m prop (1//P)` or, `m_(2) gt m_(1) :. P_(2) lt P_(1)`.
