Ideal PV=nRT

An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly eleastic and in which there are no intermolecular attractive forces.In such a gas, all the internal energy is in the form of kinetic energy and any change in internal energy is accompanied by a change in temperature.An ideal gas can be characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T).
