9th Grade- Chapter 11 & 12 Test Review

Front

What is a good insulator?

Back

A good insulator is a material that does not easily allow heat to pass through it. Examples include air, foam packing material, and down jackets.

Front

Which material is NOT a good insulator?

Back

Copper wire is NOT a good insulator; it is a conductor of heat.

Front

What is specific heat?

Back

Specific heat is the amount of thermal energy required to raise the temperature of a unit mass of a substance by one degree Celsius.

Front

What is thermal radiation?

Back

Thermal radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, from one object to another.

Front

What is a fluid?

Back

A fluid is a substance that can flow and take the shape of its container; it includes liquids and gases.

Front

What is heat?

Back

Heat is the flow of thermal energy from one object to another due to a temperature difference.

Front

What is thermal conduction?

Back

Thermal conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is thermal convection?

Back

Thermal convection is the transfer of heat by the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is latent heat?

Back

Latent heat is the amount of heat energy absorbed or released by a substance during a phase change, without changing its temperature.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.
