What are materials that do not conduct heat well?

Back

Insulators are materials that do not conduct heat well.

Front

True or False: Heat is transferred from cooler areas to warmer areas.

Back

False. Heat is transferred from warmer areas to cooler areas.

Front

True or False: As the thermal energy of matter decreases, its particles slow down and move closer together.

Back

True. As thermal energy decreases, particles slow down and come closer together.

Front

True or False: To change the temperature of different objects by the same amount, the same amount of thermal energy is required.

Back

False. Different materials require different amounts of thermal energy to change temperature.

Front

What is the amount of heat required to raise the temperature of 1 kilogram of a material by 1 kelvin?

Back

Specific Heat is the amount of heat required to raise the temperature of 1 kilogram of a material by 1 kelvin.

Front

What is a conductor?

Back

A conductor is a material that allows heat to flow through it easily.

Front

What is thermal expansion?

Back

Thermal expansion is the increase in volume of a material as its temperature increases.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself.

Front

What is the relationship between thermal energy and particle movement?

Back

As thermal energy increases, particles move faster and spread apart; as it decreases, they slow down and come closer together.

Front

What is the definition of specific heat?

Back

Specific heat is the amount of heat needed to raise the temperature of 1 kilogram of a substance by 1 degree Celsius.
