Physics Kinetic Theory of Gases Ideal Gas Equation MCQ (Single Correct)

Given is the graph between and P for 1 g of oxygen gas at two different temperatures T 1 and T 2 , as shown in figure. Given, density of oxygen = 1.427 kg m –3 . The value of PV/T at the point A and the relation between T 1 and T 2 are respectively.

A
0.259 J K –1 and T 1 < T 2
B
8.314 g J mol –1 K –1 and T 1 > T 2
C
0.259 J K –1 and T 1 > T 2
D
4.28 g J K –1 and T 1 < T 2

Verified by Experts
The correct answer is:
C

Where m = mass of the gas

And number of moles.

a constant for all values of P.

That is why, ideally it is a straight line.
