Heat: Transfer of Thermal Energy
Fun Facts
- Heating air causes it to rise, then cool and sink, forming a convection current.
- Water at the bottom of a pot rises when heated by convection, then sinks as it cools.
- Convection is used in heating homes by causing air near heaters to circulate.
Why Do We Need To Know About Convection
Learning about convection helps us know how heat moves around us and is important for making things like heaters work better. Knowing about convection can lead to jobs in designing air conditioning and heating systems.
Convection is key for making new, energy-saving technologies, better ways to cook, and fun stuff like hot air balloons. So, convection is really useful in many areas.
