Which one of the following relationships when graphed does not give a straight line for helium gas?
I. K.E. and T at constant pressure and volume
II. P v/s V at constant temperature for a constant mass
III. V v/s 1/T at constant pressure for a constant mass

Options

A. II
B. II and III
C. III
D. I

Answer

b

Explanation

(b) `KE_(T)=(3)/(2)nRT` at constant P and V
PV=K at constant T and mass
V=KT at constant P and mass
