. Volume versus temperature graphs for a given mass of an ideal gas are shown in the figure at two different values of constant pressure. What can be inferred about the relation between P1 and P2? a) P1 > P2 b) P1 = P2 c) P1 < P2 d) data is insufficient
Correct option is A) As pressure and quantity of gas in system are contant. So, by ideal gas equation PV=nRT V∝T as n,R and P are constant T1V1= costant or slope of graph is constant V=PnRT dTdV=PnR so dTdv increase when P decreases dTdV∝P1 as slope of P1 is smaller than P2. Hence P1>P2 verifies option (a)
