Which statement accurately compares cooking food with microwaves to cooking food with infared radiation

Microwave radiation utilizes short, high-frequency waves that penetrate food, which agitates its water molecules to create friction & transfer heat. If you're heating a solid substance, this heat energy is transferred throughout the food through conduction, while liquids do so through convection. Microwave heat transfer usually cooks food faster than infrared radiation, as it is able to penetrate foods several inches deep.

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.
