Heat Transfer

What is the definition of Radiation?

• The transfer of energy by electromagnetic waves, which is a form of energy that can travel through empty space.

• A type of sound wave that travels through air.

• The process of converting light into heat energy.

• A method of communication using radio waves.

What is Kinetic Energy?

• The energy an object has due to its motion.

• The energy stored in an object at rest.

• The energy released during a chemical reaction.

• The energy associated with the position of an object.

What is a Convection Current?

• The circular motion of a fluid caused by hotter, less dense fluid rising and cooler, denser fluid sinking.

• A process where heat is transferred through direct contact between materials.

• The movement of air caused by differences in atmospheric pressure.

• A phenomenon where fluids remain stationary and do not mix.

What is Convection?

• The transfer of heat through the movement of a fluid, which is a substance that can flow.

• The process of heat transfer through direct contact between materials.

• The transfer of heat through electromagnetic waves.

• The movement of air in a circular pattern without heat transfer.

Conductor Noun

---

[kuhn-duhk-ter]

• A material that allows heat or electricity to flow through it easily.

• A substance that prevents the flow of heat or electricity.

• A type of musical instrument.

• A person who leads a group or orchestra.

What is an insulator?

• A material that allows heat and electricity to pass through easily.

• A material that does not easily allow heat or electricity to pass through it.

• A type of conductor that enhances electrical flow.

• A device used to measure electrical resistance.

What is Thermal Energy?

• The total internal energy of an object due to the kinetic energy of its atoms and molecules.

• The energy stored in the bonds of chemical compounds.

• The energy associated with the motion of an object.

• The energy produced by the friction between two surfaces.

What is Conduction?

• The transfer of heat energy between objects or particles that are in direct contact with each other.

• The process of heat transfer through fluids by the movement of the fluid itself.

• The transfer of heat energy through electromagnetic waves.

• The process of heat transfer through solid materials without any movement.

Heat Transfer

• The process of converting thermal energy into mechanical energy.

• The transfer of thermal energy from a warmer substance or area to a cooler one.

• The method of storing thermal energy for later use.

• The process of increasing the temperature of a substance without heat exchange.

Fluids

• Substances that have a fixed shape and cannot flow

• Substances, including liquids and gases, that have no fixed shape and are able to flow from place to place

• Only gases that can flow and change shape

• Solid materials that maintain their shape
