What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself. Warm fluid rises while cooler fluid sinks, creating a circulation pattern.

Front

What type of heat transfer occurs in solids?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter part to the cooler part.

Front

What is thermal energy?

Back

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

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds between atoms in a molecule. It is released or absorbed during a chemical reaction.

Front

What are conductors?

Back

Conductors are materials that allow heat to pass through them easily, such as metals like copper and aluminum.

Front

What are insulators?

Back

Insulators are materials that do not allow heat to pass through them easily, such as rubber, wood, and glass.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or infrared radiation, and does not require a medium.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a rock at the top of a hill.

Front

What is kinetic energy?

Back

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

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.
