Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, and heat transfer between them stops.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight traveling through space to reach Earth.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which depends on the mass and velocity of an object.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as an object held at a height.

Front

How does heat energy travel from the sun to the Earth?

Back

Heat energy from the sun travels to the Earth through radiation.

Front

What happens to the temperature of objects in thermal contact over time?

Back

The temperatures of the objects will equalize, reaching thermal equilibrium.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection involves the movement of fluids to transfer heat.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot bowl of soup.
