Module 8 Review: Thermal Energy

A fire is an example of what kind of ENERGY?

• Nuclear

• Sound

• Thermal

• Chamical

What happens to the particles in a substance as heat/energy is added or taken away?

• They speed up or slow down.

• They stay the same.

What is known about the Kinetic energy of a gas

• Very little KE

• Lots of KE

• Same KE as a Solid

• Same KE as a liquid

Temperature

• The total kinetic and potential energy of all the particles in an object.

• Energy that is transferred from a warmer object to a cooler object.

• A measure of the average kinetic energy of the particles in a substance.

• The heating of a substance that causes its particles to move more quickly.

Heat

• The total kinetic and potential energy of all the particles in an object.

• Energy that is transferred from a warmer object to a cooler object.

• A measure of the average kinetic energy of the particles in a substance.

• The heating of a substance that causes its particles to move more quickly.

Conduction

• The transfer of energy by electromagnetic waves.

• A circular motion of air that causes wind and changes in weather

• A type of heat transfer that occurs through the movement of fluids.

• The transfer of energy from one particle of matter to another within an object or between two objects that are in direct contact.

Convection

• The transfer of energy by electromagnetic waves.

• A circular motion of air that causes wind and changes in weather

• A type of heat transfer that occurs through the movement of fluids.

• The transfer of energy from one particle of matter to another within an object or between two objects that are in direct contact.

Radiation

• A circular motion of air that causes wind and changes in weather

• The transfer of energy between two objects not in contact

• A type of heat transfer that occurs through the movement of fluids.

• The transfer of energy between two objects that are in direct contact.

Conductor

• A material with a high specific heat capacity

• A material that conducts heat well,

• The amount of energy required to raise the temperature of 1 kilogram of a material by 1 kelvin.

• A material that is poor at transferring energy

Specific Heat

• Materials that do not conduct heat well.

• A material that conducts heat well,

• The amount of energy required to raise the temperature of 1 kilogram of a material by 1 kelvin.

• The expansion of matter when it is heated.
