Question

Explain kinetic theory of gases

Answer 1

According to Kinetic Theory of gases, gases consist of tiny molecules separated from one other by means of large gaps called voids. When the temperature of the gas is lowered, the volume and the kinetic energy also decrease. As a result the molecules become slow and start coming close to each other. As the temperature is further decreased , the molecules come nearer and nearer. At a sufficiently low temperature, the voids between the particles become less than 10-5cm and the gas converts into the liquid state. This effect causes a decrease in the volume of the gas.{This process is called Liquefaction of gas, as the process of bringing the gas molecules nearer can be done by increasing the pressure of the gas}.

Answer 2

a) All gases are coposed of tiny particles called molecules.

b) They are in continues motion.

c) They collied between eacher other and with the walls of the vessels.

d) There are no attractive force between the molecules

e) Volume of the ga can br neglected compared to the total volume

f) Pressure of the gas due to the collision of molecules on the wall
