The average kinetic energy of the molecule is directly proportional to the absolute temperature.
At any given instant, the molecule do not have the same kinetic energy. There is no kinetic energy lost during collisions inspite of the transfer of energy from one molecule to another. The molecules collide with one another and with the sides of the container. Because of their mass and velocity, they possess kinetic energy, (K.E. According to this theory, all matter is made of constantly moving atoms or molecules. The behavior of gases is explained by what scientists call the Kinetic Molecular Theory. P = 1 atm or its equivalents Postulates of the Kinetic Molecular Theory Standard Temperature and Pressure (STP) or Standard Conditions (SC): At absolute zero ( 0K) molecules stop moving entirely, the gas is as cold as anything can get. 1 atm = 1 atmosphere = 760 torr = 760 mm = 76 m Hg
