Gas Law Review for Test

The kinetic theory states

• Particles won't move if you don't apply energy to it.

• Particles only move in liquids and gases.

• Particles are always in motion.

• At the same temperature the object that has the most mass heats quicker.

Which is NOT an assumption made by the kinetic molecular theory of gases?

• Gas particles are small and take up little volume
• Particles travel in constant, random, straight-line motion until colliding
• When particles collide, their total kinetic energy is decreased
• Particles do not attract or repel each other

Which of the physical states of water contains particles with the lowest kinetic energy?

• Water

• Ice

• Steam

• Melting ice

1. What is the name given to a gas whose particles follow the assumptions of the kinetic molecular theory?

• Real Gas

• Noble gas

• Ideal gas

• Diatomic gas

As the temperature of a substance increases:

• The speed, and average kinetic energy of the particles, both increase.

• The speed, and average kinetic energy of the particles, both decrease.

• The speed of the particles increases, but the average kinetic energy of the particles decreases.

• The speed of the particles decreases, but the average kinetic energy of the particles increases.

Which of the following is not one of the assumptions of the kinetic molecular theory for ideal gases?

• The particles attract and then repel each other.
• The collisions between particles are elastic
• The particles are in constant random motion.
• The particle size is very small compared to the space between the particles.

Which of the following is an assumption of the kinetic-molecular theory of gases?

• Collisions between gas particles are inelastic.

• Gases consist of closely spaced particles.

• Gas particles move around in an orderly manner.

• The temperature of a gas depends on the average kinetic energy of the gas particles.

For an ideal gas several assumptions are made about the particles including

• they collide elastically with each other and the container wall

• they experience significant intermolecular forces

• the volume they occupy as individual particles is insignificant compared to the volume of the container

• there are a very large number of particles inside the container

A hypothetical gas that perfectly fits all the assumptions of the kinetic molecular theory is known as

• real gas

• ideal gas

• imaginary gas

• perfect gas

Gas molecules can easily be compressed  because ___________. 

• gas molecules are soft
• gas molecules are far apart
• gas molecules follow the shape of the container
