QUESTION 16 According to the kinetic theory of gases, the average kinetic energy of the gas particles in a gas sample is directly proportional to the O pressure. O volume O temperature O molar mass O number of moles of gas
The kinetic theory of gases states that the kinetic energy of a gas is directly proportional to the temperature of the gas. A relationship between the microscopic properties of the gas molecules and the macroscopic properties of the gas can be derived using the following assumptions: The gas is composed of pointlike particles separated by comparatively large distances. The gas molecules are in continual random motion with collisions being perfectly elastic. The gas molecules exert no long-range forces on each...
