movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

Conduction

Effects of Radiation

the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.

ConductionConvection & Radiation.

Convection

Radiation

Real World Examples

Conduction: burning ur hand on a hot stove,Using a heating blanket to get warmUsing a heating blanket to get warmConvection: hot air rising/ falling, the inside of a greenhouse worksRadiation:heat from the sun warming something up, person placing their cold hands over a warm fire
