What is the difference between conduction and convection?

CONVECTION is the transfer of heat from high temperature to low temperature with movement of mass or medium due to temperature difference in the region. Although, convection is a bit similar to conduction, but convection involves movement of substances. Such as wind system in our planet. Air moves due to temperature difference in every part of our planet. Then, CONDUCTION is the transfer of heat, of course from high temperature to low temperature when two objects (such as metals) are in direct contact (without the movement of metals).

These are both ways heat travel. Conduction is when something is touching something i.e. When you touch a hot pan. Convection is heat rising, then cooling so it sinks and heats back up and rises again repetitively i.e. A convection oven (think circulation of heat)

Dsolubility let me know if you have any other questions for chemistry

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
