- Q1The temperature of a gas in a rigid steel container is increased from 100 K to 200 K. Which of the following is the most likely effect of this change on the other three variables used to describe the behavior of a gas?The mass and volume of the gas is halved, while the pressure remains constant.The pressure of the gas is doubled, while the volume and mass remain constantThe volume of the gas is halved, while the pressure and the mass remain constant.The pressure and volume of the gas are doubled, while the mass remains constant.30s112.35.c.9.a

- Q3When a gas is ideal, there is no loss of energy during collisions. Which postulate of the kinetic molecular theory BEST supports this statement.The kinetic energy of gas particles is directly proportional to temperature.Gas particles are in constant random motion.There are no interactive forces between particles of gases.Collisions between gas particles are elastic.30s112.35.c.9.b
- Q4Which postulate of the kinetic molecular theory BEST explains why gases can be compressed?There is no force of attraction between gas particles.There is empty space between gas particles.Gases are in constant random motion.Gas particles move in a straight line until they collide with other matter.30s112.35.c.9.b
- Q5Which of the following is NOT a postulate of the Kinetic Molecular Theory?There are no attractive or repulsive forces between particles.The average speed of particles is proportional to the temperature.Larger particles exert more pressure at a given temperature.Particles move in straight lines until the collide with something.30s112.35.c.9.b
- Q6Two gas molecules collide together in a box container. Which reaction accurately portrays the kinetic molecular theory?The two molecules will either be attracted or repelled by each other depending on the charge of each gas molecule.The two molecules will move in different directions without being attracted or repelled by the other.The two molecules will move off in opposite directions because they are repelled by each other.The two molecules will stay together because they are attracted to each other.30s112.35.c.9.b
