Thermal Energy & Heat Review

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total energy of all the particles in an object.

Front

What is heat?

Back

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

Front

Which material acts as the best insulator?

Back

Styrofoam is the best insulator among the options provided.

Front

What happens to heat when a hot object is placed in a cooler environment?

Back

Heat moves from the hot object to the cooler environment until they reach the same temperature.

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases). Warm air rises and cool air sinks.

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 happens to the movement of molecules when they are heated?

Back

The movement of the molecules speeds up when they are heated.

Front

What happens to warm air compared to cold air?

Back

Warm air is less dense than cold air and rises, creating convection currents.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon gets hot after being placed in a hot soup.
