Thermal Energy

Which is NOT a part of Kinetic Molecular Theory?

• All matter is made of particles

• Particles only move when they increase in temperature

• Particles are in constant, random motion

• Particles collide with each other and their containers

_______ is the measure of the average kinetic energy of the particles of a material.

What will happen to the particles in a material if temperature is increased?

• Their kinetic energy will increase

• They will move slower

• Their kinetic energy will decrease

• They will catch on fire

What is the movement of thermal energy from an area of higher temperature to an area of lower temperature?

• Kinetic energy

• Thermal equilibrium

• Insulation

• Heat

What will happen to the thermal energy of a cold glass of water after it is placed in a warm room?

• The thermal energy in the water will be destroyed

• Thermal energy from the room will transfer to the water

• Thermal energy from the water will transfer to the room

• The cold energy of the water will be replaced by warm energy

Thermal energy will continue to transfer between materials until the temperature of both materials are the same. This is called

• Convection

• Temperature regulation

• Thermal equilibrium

• Kinetic Molecular Theory

What is the transfer of thermal energy from one object to another by electromagnetic waves?

You put your hand onto a cold stair railing in the winter. Your hand feels cold as thermal energy escapes your warm skin. This is an example of

• Conduction

• Radiation

• Convection

• Insulation

A transfer of thermal energy by the movement of particles in a fluid. Warm particles rise and colder particles sink.

• Conduction

• Radiation

• Convection

• Temperature

Which state of matter has particles that are closest together and moving the least?

• Solid

• Liquid

• Gas

• Plasma
