The p-T graph for the given mass of an ideal gas is shown in figure. What inference can be drawn regarding the change in volume (whether it is constant, increasing or decreasing) ?

Options

A. remained constant
B. decreased
C. increased
D. changed erratically

Answer

C

Explanation

p-T equation from the graph should be like.
p= aT +b (a and b are positive constants )
`therefore" "p/T=a+b/T rArrT_(2) gt T_(1)`
`therefore" "(p/R)_(2) gt (p/T)_(1)or (T/p)_(2) gt (T/p)_(1)`
or `therefore" "V_(2) gt V_(1)as V propY/p`
