Which improves air circulation in forced air heating? a, radiation b, conduction, c, convection

Convection

Explanation:

As we know that in convection mode of heat transfer the medium molecules is transferred from one part to other part along with the thermal energy stored with them.

Here when heat is given to the medium then due to temperature gradient density of medium will change and this will lead to a movement of medium particles from higher density to lower density region.

This is known as convection mode of heat transfer and this mode of heat transfer can be increased by forced convection of medium particles.

So here air circulation in forced heating is an example of CONVECTION

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

the answer is b ) square root of 5
