CBSE Ncert Notes for Class 11 Chemistry States of Matter. States of matter. Matter can be categorised into three states. Hitherto five states of matter are known, viz, solid, liquid, gas, plasma and Bose-Einstein condensate. Out of these solid, liquid and gas are. require knowledge of the state of matter. Therefore, it becomes necessary . of matter in these states. We shall deal with the solid state in class XII. .. Page

If the critical temp of a gas is higher then it is easier to liquefy.

That is the intermolecular forces of attraction among the molecules of gas are directly proportional to its critical temp. Measurable properties of gases: P,V, T, n, Viscosity, specific heat are some measurable properties.

The pressure of fixed msss of gas varies inversely with the volume at constant T. At constant P, the states of matter class 11 of fixed amount of gas varies directly with its absolute temperature.

At constant V, The pressure of fixedamount of gas varies directly with its absolute temperature. At given T and P, the volume of gasvaries directly to the amount of gas.

T, V, constant This equation can states of matter class 11 derived by considering a real gas and converting it to an ideal gas. Therefore due to n moles of a gas the volume excluded would be nb. Let us assume that the real gas exerts a pressure P. The molecules that exert the force on the container will get attracted by molecules of the immediate layer which are not assumed to be exerting pressure.

It can be seen that pressure the real gas exerts would be less than the pressure an ideal gas would have exerted. Therefore if a real gas exerts a pressure P, then an ideal gas would exert a pressure equal to P p p is the pressure lost by the gas molecules due to attractions. This small pressure p would be directly proportional to the extent of attraction states of matter class 11 the molecules which are hitting the container wall and the molecules which are attracting these.

A gas consists of large number of small particles, called molecules. Volume occupied by gas molecules, is negligible as compared to the total volume of the gas.

There is continuous rapid random motion of gas molecules. The molecules collide with each other and with the walls of container.

The molecules are perfect elastic bodies and there is no loss of kinetic energy during collisions. There are no attractive forces between the gaseous molecules.

The pressure exerted by a gas is due to the bombardment of gas molecules against the walls of the container. The different molecules possess different velocities and hence, different energies.

The average KE is directly proportional to absolute temperature.
