Answer:
(a) more than
Explanation:
Conduction:
Transfer of heat due to direct contact between two mediums at different temperatures, without having any of the bodies traveling. Therefore, conduction heat transfer occurs by the transfer of momentum (molecular) from always the same group of molecules in one medium to another group of molecules in another medium.
Example: Heat transfer INSIDE a solid.
Convention:
Transfer of heat or mass due to at least one traveling medium, where the transfer of momentum is not bounded anymore to the same groups of molecules. Molecules moving to transfer their momentum and keep flowing to the next group, also allowing other molecules behind to do the same. Example: heat transfer by the wind.
Hence, the Mass transfer rate in convection is <u>more than</u> mass transfer in conduction
Answer:
Tin(IV) Oxide + Carbon = Tin + Carbon Monoxide
Explanation:
In this reaction the products have less potential energy than the reactants.
A scheme of a chemical reaction. The reactants are two molecules, one of which consists of A and B, and the other consists of C and D.
The products are two molecules, one of which consists of A and C, and the other consists of B and D.
The energy of molecules AB and CD is higher than the energy of molecules AC and BD.
In this reaction heat has been released to the environmen.
