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:
An element that belongs to group 17 of the periodic table is a halogen, and will have physical and chemical characteristics like that of nonmetals.
Explanation:
Halogens are nonmetals, and include five elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They are all nonmetals, and are quite toxic.
Halogens become darker as you go down the group. Fluorine is a very pale yellow, while bromine is red-brown. Halogens have relatively low melting and boiling points as well.
