Jacques Alexander Cesar Charles, a French chemist, discovered in 1787, that at a constant pressure, with rise in temperature, carbon dioxide, hydrogen, oxygen and nitrogen, all expanded at constant rate..

At a given pressure, the volume of a given mass of a gas is proportional to its absolute temperature. This is Charles' law. From (a), if p is constant in expression (a), we get , which is Charles' law..

When a gas is heated the molecules move faster increasing the pressure. But to maintain the pressure constant, the force of collision is compensated with an increase in volume. So, at constant pressure the volume of the gas increases with temperature. By kinetic gas equation we have, subst..

"At constant pressure, the volume of a given mass of gas increases or decreases by 1/273 of its original volume at 32 o F, for each degree centigrade rise or lowering in temperatur..

Example 1:- A given mass of a gas occupies 960 ml at 27 o C. What volume will it occupy if the temperature is raised to 177 o C, pressure remaining constant. Solution:- V 1 = 960 ml V 2 =? T 1 = (27 o C + 273) = 300 K T 2 = (177 o C) = 273 = 450 K Substitution the values Hen..

At a given volume, the pressure of a given mass of a gas is proportional to its absolute temperature. This is Charle's law for pressure. This is the definition of the absolute temperature, T. If one starts from the fact that T and uses the fact that V is constant, one gets..
