Heat Transfer

Heat Transfer

is the process by which thermal energy moves from a warmer object to a cooler one, occurring through conduction, convection, or radiation.

Conduction

is the transfer of heat through materials by direct contact, where faster-moving particles collide with slower ones, transferring energy.

Convection

is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself, often resulting from temperature differences that create flow.

Thermal Radiation

is the transfer of heat through electromagnetic waves without requiring a medium, allowing thermal energy to travel through a vacuum.

Temperature

is a measure of the average kinetic energy of the particles in a substance, often perceived as the degree of hotness or coldness.

Thermal Energy

is the total energy of a substance due to the kinetic energy of its particles.

Thermal Conductor

is a material that allows heat to flow through it easily

Thermal Insulator

is a material that reduces the transfer of heat between objects

Thermal Expansion

is the increase in volume of a substance when it is heated, due to the increased kinetic energy of its particles.

Electromagnetic Spectrum

is the range of all types of electromagnetic radiation, including gamma rays, X-rays, ultraviolet, visible light, infrared, microwaves, and radio waves, categorized by wavelength and frequency.
