Thermal Energy

Front

What is thermal energy?

Back

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

What is a conductor?

Back

A conductor is a material that allows heat or electricity to flow through it easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to flow through it easily. Examples include rubber, glass, and Styrofoam.

Front

What does the Kinetic Theory of Matter state?

Back

The Kinetic Theory of Matter states that all particles of matter are in constant motion, and this motion increases with temperature.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light. It does not require a medium to travel through.

Front

What happens to molecules when matter changes from solid to liquid?

Back

When matter changes from solid to liquid, the molecules expand and speed up due to increased thermal energy.

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 no heat flows between them.

Front

What is the role of thermal energy in weather patterns?

Back

Thermal energy from the sun heats the Earth's surface unevenly, causing air to circulate and create weather patterns.
