5.09 Quiz: How Heat Moves

Heat Transfer Methods

• Heat transfers through three primary processes: conduction, convection, and radiation.
• Conduction occurs when heat moves through a solid object, typically requiring direct contact between molecules.
• Convection involves the movement of fluids (liquids or gases) that carry heat as they circulate.

Role of Fluids in Heat Transfer

• Convection requires fluids, which can be either liquids or gases, to effectively transfer heat energy.
• Movement in these fluids is essential; warmer regions rise, while cooler regions sink, creating a continuous cycle.

Insulators and Heat Transfer

• Insulators are materials designed to slow down the transfer of heat.
• Common insulators include rubber, plastic, and glass, which are used to maintain temperature by preventing heat escape.
