Thermal Energy

Front

What is specific heat?

Back

The specific heat is the amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.

Front

What type of heat transfer is demonstrated by walking on warm sand?

Back

Conduction.

Front

Which heats up faster: 100 mL of water or 1000 mL of water?

Back

100 mL of water heats up faster.

Front

What type of heat transfer occurs when grabbing a hot pot handle?

Back

Conduction.

Front

What does a high specific heat indicate?

Back

It requires more energy to change temperature.

Front

Define conduction in the context of thermal energy.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

Define convection in the context of thermal energy.

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

Define radiation in the context of thermal energy.

Back

Radiation is the transfer of heat through electromagnetic waves without the need for a medium.

Front

What happens to the temperature of a substance when it absorbs heat?

Back

The temperature of the substance increases.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.
