The pressure of a gas in a sealed container is 152 mm Hg. This translates to what?
Weegy: 1 mm Hg = 1 torr 760 torr = 1 atm 152 mm Hg /1 * 1 torr/ 1 * 1atm/760 torr = .2 atm User: Which of the following is a postulate of the kinetic-molecular theory? A. Gases are made up of particles that act like small, hard spheres that are always moving in a calculated fashion. B. Gas particles travel in a random pattern until they hit a container wall or another gas particle. C. The distance between gas particles is equal to the size of the particles themselves. D. Gas particles have no force of attraction on one another or to the walls of the container. Weegy: B. Gas particles travel in a random pattern until they hit a container wall or another gas particle.
