what is the different between conduction and convention?

Question

it is about weather

Answer 1

There are three ways to transfer heat: conduction, convection, and radiation.

Conduction - Transfer of heat through molecular contact. Basically molecules moving faster hit molecules travelling more slowly and transfer some of their energy, causing the slower ones to speed up.

Convection - Transfer of heat through fluid motion. "Chunks" or "parcels" of liquids or gases that are hotter and less dense rise and cooler ones sink, distributing heat much more efficiently than would occur through conduction only.

Radiation - Substances emit electromagnetic radiation based on their temperature. This can be absorbed by other substances, heating them.

Notice that for liquids and gases, convection can only occur AFTER conduction or radiation heats or cools them.

Answer 2

convection is where fluids (gas/liquid) at different temeratures move around transferring heat. E.g. a fan oven using convection to heat the oven.
Conduction works in solids too. It is where heated atoms heat atoms next to them and so on. Putting an iron rod in a fire and feeling the heat in your hand is an example.

Convection happens a lot in weather systems.

Answer 3

Conduction- heat transfer through a solid
Convection- heat transfer through a liquid or a gas

Answer 4

You mean convection, I think?
And radiation is heat transference through a gas eg the air

Answer 6

I think you're using a wrong word! You probably mean conveCtion, not conveNtion.
further info in your dictionary!! You need the experience of using a dictionary.

Answer 7

***Convection*** is heat transfer through a fluid.
Conduction is heat transfer through a solid.
