Answer:
1.3 x 10²⁴ atoms Fe
Explanation:
To convert moles to atoms, you need to multiply your given value by Avogadro's Number. This causes the conversion to occur because Avogadro's Number exists as a ratio. It is the ratio that allows for the cancellation of units during multiplication. This is why atoms should be in the numerator of your conversion. The final answer should have 2 sig figs to reflect the given value.
Avogadro's Number:
1 mole = 6.022 x 10²³ atoms
2.1 moles Fe 6.022 x 10²³ atoms
--------------------- x ------------------------------- = 1.3 x 10²⁴ atoms Fe
1 mole
Am not exactly sure but i think ots conduction

Explanation:
They are two representatives of the sublevels/energy levels.
Heat can be transferred from one object to another in 3 different ways.
1) Conduction : This is the mode of transfer of heat through solid medium.
Example : A metal rod getting hot when hold over a flame.
2) Convection : This is the mode of transfer of heat through liquids
Example : Boiling of water.
3) Radiation : This type of heat transfer does not require any medium.
Example : When we stand close to a campfire, we feel warmer. Here the heat travels through air.
In the given problem, when a person gets into a car with hot black leather, his skin comes in contact with the hot object. Here the heat gets transferred through the skin which is a solid medium.
Therefore this is an example of conduction.
