physical properties of a gas

. So, the heat supplied is assumed to increase only the temperature. However, the coefficient of expansion is very large in case of gases. Thus, if a gas is heated the heat energy is required, not only to increase the temperature of the gas but also to do mechanical work in over..

The glass discharge tube is filled with a 80%-20% mixture of the inert gases helium and neo..

Forces at a distance Are equal and opposite. Depend upon the distance between the two objects. Depend upon the medium between the two objects for electrical and magnetic forces but not gravitational forces. Forces are described in different names. Some forces are shown in the following d..

v . If M is the molecular weight of the gas in gram, then Let an amount of heat dQ be supplied to one gram mole of a gas at constant volume. Let dT be the increase in temperature. The molar specific heat of a gas at constant pressure is defined as the amount of hea..

(i) g -rays are not deflected by electric and magnetic fields and this shows that they do not have any charge. (ii) The rest mass of g -ray photon is zero. (iii) The g -rays travel with the speed of light. (iv) g -rays have a very large penetrating power and small ionizing power. (v) g -rays ..

(i) a - rays consists of a -particles carrying double positive charge having a mass roughly four times that of hydrogen atom. (ii) Due to large mass, their penetrating power is very small. (iii) Due to large mass and velocity they have a large ionizing power. (iv) a - rays produce fluorescen..

Whenever a wave passes through a medium, there is a change in some property of the medium. Hence, the waves can be graphically represented by showing the changes in the value of any such property of the medium as the waves travel through ..

The States of Matter - Matter occurs in four states: Solid, Liquid, Gas and Plas..
