Worksheet KEY Gases 1. Convert 444 mmHg to torr and atm 1 atm = 760 mmHg = 760 torr so P = 444 torr = 0.579 atm 2. Convert 2.0 atm to torr and mmHg. P = 1520 torr = 1520 mmHg 3. Indicate whether each of the following statements is true or false for an ideal gas. a. The distance between gas particles is about 10 times the diameter of a gas particle. False – The average distance is much longer b. Gas particles usually move in curved pathways. False – Gas particles move in straight-line paths between collisions c. Gas particles repel each other when they get too close to each other. False – There are no repulsive (or attractive) forces between gas particles in an ideal gas. d. The average velocity of the gas particles in a container will always increase when the temperature is increased. True – The velocity is proportional to kinetic energy and kinetic energy increases with temperature. e. When the temperature of a gas is held constant and the volume is decreased, the pressure exerted by a gas will also decrease. False – The pressure increases when volume decreases. f.
