Which of the following is not an assumption of the kinetic theory of gases?
A gas consists of many identical particles which are in continual motion.
Gas particles have negligible volume.
At high pressure, gas particles are difficult to compress.
Collisions of gas particles are perfectly elastic.
Statement 3 is wrong it should be-
At high pressure, gas particles are easy to compress.
we know PV = nRT
P = nRT/V
as P increases - V decreases - T increases
Other statements are right.
