• Convection is the process of heat transfer through a fluid (liquid or gas) by the movement of the fluid itself.

Convection Current

• Convection current is when the particle from a hotter temperature move to a cold temperature

• Example - a pot of soup heating on the stovetop from a conductor

2 Types Of Convection

• Natural Convection

• Forced Convection

Natural Convection

• Occurs due to natural differences in temperature.

• Warm fluid becomes less dense and rises; cooler fluid is denser and sinks.

Forced Convection

• External force like a fan moves the fluid.

Convection And Conduction Difference

• In convection, energy is transferred through a material from a warmer place to a cooler place by the movement of the material itself.

• In conduction, energy is transferred through a material from a warmer place to a cooler place without the material itself moving.
