The volume versus temperature graph for a certain amount of a perfect gas at two pressure `P_1` and `P_2` are shown in figure. Which one is greater `–P_1` or `P_2` ?

Explanation

`"pV = nRT"`
`:." "V = ((nR)/(p))T`
Comparing this with `Y = m x, V - T`. Graph is a straight line passing through origin with slope` = (nR)/P`
or slope `prop 1/p("slope")_1 gt ("slope")_2" ":." "P_1 lt P_2`
