Chapter 5- Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which is related to its temperature.

Front

What is heat?

Back

Heat is the transfer of thermal energy from a warmer object to a cooler object.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.

Front

What are conductors?

Back

Conductors are materials that allow heat to flow through them easily, such as metals.

Front

What are insulators?

Back

Insulators are materials that do not conduct heat well, such as rubber, wood, and plastic.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, such as sunlight.

Front

Why does sand heat up faster than water?

Back

Sand has a lower specific heat than water, meaning it requires less energy to increase its temperature.

Front

What is a fluid?

Back

A fluid is a substance that can flow, which includes liquids and gases.
