A gas present in a container connected to frictionless, weightless piston operating always at one atmosphere pressure such that it permits flow of gas outside (with no adding of gas.). The graph of n vs T (Kelvin) was plotted & was found to be a straight line with Co-ordinates of extreme points as (300, 2) & (200, 3). Calculate
(i) relationship between n & T
(ii) relationship between V & T
(iii) Maxima or minima value of ‘V’
