Key concepts
3 concepts
- 1
In solids, heat is transferred by conduction, in fluids it is transferred by convection, and through empty space it is transferred by radiation.
- 2
Thermal conductivity determines how well objects transfer energy by conduction; metals have high thermal conductivity, while plastics and fluids have low thermal conductivity.
- 3
In convection, warmer, less dense fluid rises, while cooler, more dense fluid sinks, creating a convection current.
