Gas Laws - Coming Soon
... An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly elastic and in which there are no intermolecular attractive forces. One can visualize it as a collection of perfectly hard spheres which collide but which otherwise do not interact with each other. In suc ...

The second law of thermodynamics
... So far we have considered the equilibrium of isolated systems. Now let us look at a system which is in contact with a heat bath having temperature T . A heat bath is a body with a heat capacity very large compared to the system in question. This implies that the system and the heat bath can come to ...
