There are three characteristics of gas which describe its behaviour. These are pressure(P), volume(V) and temperature(T). The relation among pressure, volume and temperature of a gas is given by these two laws. (1) Boyle’s Law It is given by English chemist Robert Boyle (1627-1691). According to this law at constant temperature, pressure is inversely proportional […]
These are the waves in which the individual particles of the medium oscillate along the direction of wave propagation. We consider a long hollow cylinder AB closed at one end and having a movable piston at the other end. If we suddenly move the piston rapidly towards right, a small layer of air just near
These are the waves in which the individual particles of the medium oscillate perpendicular to the direction of the wave propagation. Example: Waves in string, ripples on the surface of water, movement of sting of stringed musical instruments like sitar, guitar etc. We consider a horizontal string with its one end fixed to a rigid
Propagation Of Sound Wave Through Air A small region of air can be considered as a spring. It is connected to the neighbouring regions or springs. As sound wave travels through air, it compresses or expands a small region of air. This changes the density and pressure of the region. According to Boyle’s law Change
We consider a collection of springs connected to one another and one end is fixed to a rigid support. If the spring at one end is pulled suddenly and released, the disturbance travels to the other end. The reason behind this is when the first spring is pulled, it gets stretched. Due to elasticity, a
The total number of co-ordinate or independent quantities required to describe completely the position and configuration of a dynamic system is known as number of degree of freedom of the system. It is represented by f and expressed as (I) In case of monoatomic gas, such a helium, neon, organ, kripton, etc have translational degree
All matter is made up of molecules. The molecules of a gas are in state of rapid and continuous motion. Their velocity depends on temperature. Using this molecular motion, various properties of a gas like pressure, temperature, energy etc, can be explained. Hence this theory is called kinetic theory of gases which was developed by
Boyle’s Law It state that for a given mass of a gas at constant temperature, the volume(V) of that mass of gas is inversely proportional to its pressure(p). Charles’ Law It state that for a given mass of an ideal gas at constant pressure, volume (V) of a gas is directly proportional to its absolute
The molecules of gas are far from each other and their mutual interactions are negligible except when two molecules collide. So, gases at low pressure and high temperature much above that at which they (liquify or solidify) follow a relation pV = KT -(i) Behaviour Of Real Gas and Ideal Gas An ideal gas is
