Heat Transfer
Types of heat Transfers
convection
the process in which heat moves through a gas or a liquid as the hotter part rises and the cooler, heavier part sinks
Radiation
the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: electromagnetic radiation, such as radio waves, etc

How does it work
Convection
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. ... The denser cold liquid or gas falls into the warm areas.
Radiation
Radiation works by making small breaks in the DNA inside cells. These breaks keep cancer cells from growing and dividing and cause them to die. Nearby normal cells can also be affected by radiation, but most recover and go back to working the way they should.
Conduction
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules.These vibrating molecules collide with their neighboring molecules, making them also vibrate faster. As these molecules collide, thermal energy is transferred via conduction to the rest of the pan.
Benefit and consequences
With heat transfers, it's possible to react quickly to large or small orders, reducing lead times by over 50% compared to that of screen printed apparel. Heat transfers are also perfect for selling decorated apparel online when the average order size is just one or two shirts in different sizes, colors and styles.
The body can also gain or lose heat through mechanisms of heat exchange. Conduction transfers heat from one object to another through physical contact. Convection transfers heat to air or water. Radiation transfers heat via infrared radiation.
