TRUE. (Lorenzo Romano Amadeo Carlo Avogadro) Ideal Gas Law that defined as one in which all collisions between atoms or molecules are perfectly elastic in which there are no intermolecular attractive forces. In such a gas, all the internal energy is the form of kinetic energy and any change in internal energy is accompanied by a change in temperature. That characterized by three state variables: absolute pressure (P) = 1 atm, volume (V) = 22.4 L and absolute temperature (T) = 273 K.
