second law is the real law

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..

The study of behaviour of gases has led to the formulation of a few important generalisations called as Gas Laws..

Laws of Thermodynamics - Zeroth Law - 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 ..

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 temperatur..

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 hi..

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 volume and pressure of a given mass of dry gas is..

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..

All thermochemical reactions are governed by two laws..

There are nearly 14 laws of conservation based on symmetry principles in physics. Anything that happens must not be forbidden by a conservation law, some of the important ones a..
