1 point Q A macroscopic sample of gas in thermal equilibrium at temperature Tcontains two types of molecules, oxygen, with molecular mass 32u and nitrogen with molecular mass 28u. Which of these statements about the gas molecules is true? In thermal equilibrium, every oxygen molecule has the same kinetic energy and every nitrogen molecule has the same kinetic energy, but the oxygen molecules do not have the same kinetic energy as the nitrogen molecules. In thermal equilibrium, every molecule has the same speed In thermal equilibrium, every molecule has the same kinetic energy 0 The average kinetic energy per oxygen molecule is greater than the average kinetic energy per nitrogen molecule. The average speed of the nitrogen molecules is greater than the average speed of the oxygen molecules Previous Next
