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 (whtherit is constant, increasing or decreasing) ?

Explanation

Form th given graph we can write the `p-T` equation as,
`" " p/T=a+b/T`
now, `" " T_(B)gtT_(A)`
`therefore" " b/T_(B)ltb/T_(A)`
or `" " (p/T)_(B)lt(p/T)_(A)`
or `" " (T/p)_(B)gt(p/T)_(A)`
or `" " V_(B)gtV_(A)`
Thus, us we move from A to B, volume of the is increasing.
