A planet moves around the sun in such a way that the square of its time period is proportional to the cube of the semi-major axis of its elliptical orbit. If T is the time period of revolution and 'a' the semi-major axis then, for circular orbits a = r (radiu..

Gas Laws - Boyle's Law - The study of behaviour of gases has led to the formulation of a few important generalisations called as Gas Laws..

Gas Laws - Charles' Law - 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 rat..

The 'zeroth law' states that 'if two bodies (say A and B) are in thermal equilibrium with another body C, then the bodies A and B will also be in thermal equilibrium with each other'. This law is important as it helps in understanding the concept of temperature. This means that ..

Boyle's Law Robert Boyle proposed this law in the year 1662, giving the relationship between pressure and volume of given mass of a gas at constant temperature. This law states that volume (V) of a given mass of gas is inversely proportional to the pressur..

Gas Laws - Boyle's Law - The volume of a given mass of a dry gas is inversely proportional to its pressure, temperature remaining constant. Robert Boyle (1627 - 1691) discovered this law in 1662 and it was named after him. It can be restated as "The product of the volu..
