Heat is transferred from the heating element to the pot to the boiling water. what is the most likely method of heat transfer?

Conduction

Explanation: There are three modes of heat transfer.

1. Conduction: This type of heat transfer happens when there is direct contact between the two object.

2.  Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas).

3.  Radiation: This type of heat transfer happens when there is direct transfer of energy through space.

Thus heat being transferred from the heating element to the pot to the boiling water is an example of conduction as the they are in direct contact with each other.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.
