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.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
