Thermal Energy Unit Test

Front

What is thermal energy?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of heat from a hotter object to a colder object through direct contact.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or infrared radiation.

Front

What is the role of a thermometer?

Back

A thermometer is a tool used to measure the temperature of a substance.

Front

How does color affect heat absorption?

Back

Darker colors absorb more heat than lighter colors, which reflect more light.

Front

What is the purpose of insulation?

Back

Insulation is used to reduce heat transfer between objects, keeping heat in or out.

Front

What materials are good conductors of heat?

Back

Metals like copper and aluminum are good conductors of heat.

Front

What materials are good insulators?

Back

Materials like wood, glass, and plastic are good insulators.

Front

What happens to particles in a substance when it is heated?

Back

When a substance is heated, its particles gain energy and move faster, increasing the temperature.
