Module 8 Review

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.

Gas pressure is caused by

• gas molecules colliding with surfaces
• gas molecules condensing to a liquid
• gas molecules hitting other gas molecule
• barometers

According to the Kinetic Molecular Theory a liquid's (SELECT ALL THAT APPLY)

• particles are held close together by intermolecular forces

• particles are in constant motion

• particles are vibrating in place and closely packed

• particles are not moving

Of these three states of matter, which one has the most kinetic energy? 

• Solid 
• Liquid 
• Gas

Solids are described as having a 

• definite shape and indefinite volume
• indefinite shape and indefinite volume
• definite shape and definite volume
• indefinite shape and definite volume

From 30 degrees to 55 degrees, what state of matter is the substance?

• Solid
• Liquid
• Gas
• Plasma

The energy of an object as it is in motion is defined as

• Kinetic Theory
• Kinetic energy
• Potential energy
• Electric energy

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.

In which state of matter are the particles moving the least random

• Gas
• Liquid
• Solid
• Plasma

In which state of matter are the particles only vibrating?

• Gas
• Liquid
• Solid
• Plasma
