Thermal Energy

Front

What is thermal energy?

Back

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

Front

How does mass affect thermal energy?

Back

An object with more mass has more thermal energy because it contains more particles that can move and store energy.

Front

What is the relationship between temperature and kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What are the three methods of thermal energy transfer?

Back

The three methods are conduction, convection, and radiation.

Front

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is radiation?

Back

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

Front

How does heat flow between objects?

Back

Heat flows from warmer objects to cooler objects until thermal equilibrium is reached.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat to each other because they are at the same temperature.

Front

What is the difference between temperature and thermal energy?

Back

Temperature measures the average kinetic energy of particles, while thermal energy is the total energy of all particles in a substance.
