b) measure the temperature at noon everyday
p. s this is science

clouds form

solid ice forms on leaves.

water droplets form on grass.

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.

idk what is it? is this a question that you know the answer or u dont
