NGSS.MS-PS3-4

Transfer of heat by the movement of a fluid caused when a heat source causes that fluid to become less dense and rise. This rising fluid allows denser fluid to flow in toward the heat source, perpetuating the process.

• Convection

• Conduction

• Thermal Radiation

A material that allows heat to easily pass through it.

• Conductor

• Insulator

• Resistor

• Capacitor
