Air will expand about the same amount as propane with the same change in temperature over ordinary temperature ranges.

Yes this is true

Explanation:

i have the same question for chemistry, do you have the answer?

Explanation:

what does the table look like

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.
