Question

what is convection current​

Answer 1

Answer:

please mark this brainllist answer and follow me.

Explanation:

Convection is one of the three main types of heat transfer, the other two being conduction and radiation. Unlike the other two, convection can only happen in fluids. This includes liquids and gases and is because the molecules have to be free to move.

Heat energy can transfer by convection when there is a significant difference in temperature between two parts of a fluid. When this temperature difference exists, hot fluids rise and cold fluids sink, and then currents, or movements, are created in the fluid. But why does this happen? Let's look at an example of convection in action to get a better understanding.

A convection current is a process which involves the movement of energy from one place to another. It is also called to as convection heat transfer.

These things happen as a result of the Convection Currents. The convection currents tend to move a fluid or gas particles from one place to another.

A simple example of convection currents is warm air rising toward the ceiling or attic of a house. Warm air is less dense than cool air, so it rises. Wind is an example of a convection current.
