KMT Basics

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.

Which states of matter do NOT have a fixed shape?

• gases and liquids

• liquids and solids

• gases only

• liquids only

The movement of gas molecules is greatly affected by _________.

• the shape of the container
• size of the container
• temperature of the container

The energy of movement is defined as

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

Gas molecules can easily be compressed  because ___________. 

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

Temperature is the ________ of energy.

• Transfer
• Measure

The kinetic molecular 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.

If you spray air freshener on side of the room, why is there a delay for the smell to reach the other side of the room? 

• Attractive forces between air and air freshener particles
• Not enough air freshener particles
• Because the particles like where they are at
• Collisions between air and air freshener particles

In which state of matter are the particles only vibrating?

• Gas
• Liquid
• Solid
• Plasma

The slower the particles in a substance move,

• the colder it is.

• the warmer it is.

• the more energy it has.

• the less energy it has.
