Kinetic Molecular Theory

According to the kinetic molecular theory, ideal

gas particles

• are separated by small distances relative to their size

• do not transfer energy when they collide with each other

• have attractive forces between them

• move in random, constant, straight-line motion

State a change in pressure that will cause a gas in a cylinder to behave more like an ideal gas.

• Increase

• Decrease

• Remain the Same

According to the kinetic molecular theory, which statement explains why an ideal gas can be compressed to a smaller volume?

• The motion of the gas particles is circular and orderly

• The force of attraction between the gas particles is strong.

• As the gas particles collide, the total energy of the system decreases.

• The gas particles are separated by great distances relative to their size.

Under which conditions of temperature and pressure does a sample of propane behave least like an ideal gas?

• 250. K and 1.0 atm

• 250. K and 5.0 atm

• 500. K and 1.0 atm

• 500. K and 5.0 atm

Under which conditions of pressure and temperature is a real gas most like an ideal gas?

• low pressure and low temperature

• low pressure and high temperature

• high pressure and low temperature

• high pressure and high temperature

Which statement describes the particles of an ideal gas, based on the kinetic molecular theory?

• There are attractive forces between the particles.

• The particles move in circular paths.

• The collisions between the particles reduce the total energy of the gas.

• The volume of the gas particles is negligible compared with the total volume of the gas.

State a change in temperature that will cause a gas in a cylinder to behave more like an ideal gas.

• Decrease

• Increase

• Remain Constant

According to the kinetic molecular theory, which statement describes the particles in a sample of an ideal gas?

• The particles are constantly moving in circular paths

• The particles collide, decreasing the total energy of the system.

• The particles have attractive forces between them.

• The particles are considered to have negligible volume.
