Question

What do you mean by convection?


Please answer

Answer 1

$\huge\fbox{\sf{\red{Convection}}}$

Convection is a type of heat transfer that occurs due to the difference in temperature between two objects that are supplied with heat.

Here the hot substance is found in the top and cooler substance is found below it. The hot substance and the cooler substance interchange their places by the means of circular motion.

The same theory is applied for keeping the ACs at the top and room heaters on the ground.

$\blue{\sf{Examples:-}}$

• fans
• water boiling
• sea breeze
• land breeze
• radiator
