The kinetic molecular theory relates macroscopic properties such as pressure, volume, and temperature to the microscopic motions of gas particles. Consider the following statements: A. The particles in a gas experience repulsive forces that push them away from each other. B. The average kinetic energy of a gas is proportional to the temperature of the gas in kelvin. C. The pressure exerted by a sas is the result of collisions between the gas particles and the walls of the container. Which statements are true according to the kinetic molecular theory? Choose 1 answer: A B only B Aand B C Aand C D Band C

The kinetic molecular theory relates macroscopic properties such as pressure, volume, and temperature to the microscopic motions of gas particles. Consider the following statements: A. The particles in a gas experience repulsive forces that push them away from each other. B. The average kinetic energy of a gas is proportional to the temperature of the gas in kelvin. C. The pressure exerted by a sas is the result of collisions between the gas particles and the walls of the container. Which statements are true according to the kinetic molecular theory? Choose 1 answer: A B only B Aand B C Aand C D Band C

Answer 1

D Band CAccording to the kinetic molecular theory, the average kinetic energy of a gas is proportional to the temperature of the gas in kelvin (statement B), and the pressure exerted by a gas is the result of collisions between the gas particles and the walls of the container (statement C). Statement A is incorrect because gas particles are assumed to have negligible forces of attraction or repulsion between them.
