Describe convection as a type of heat transfer.
Plz help ASAP!!

heat transfer is from sitting somehere near a heat source for example a fire or a person or a light

Explanation:

Convection is a type of heat transfer by a concentration of the motion from fluid or moisture that either comes from air or water when it is heated which makes the fluid move away from the source of heat and carries the energy with it.

im not in connections yet but i might can you some questions. what grade are you in?

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
