Solid Carbon reacts with gaseous fluorine to produce gaseous carbon tetrafluoride.

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

Volume is a measurement of how fast particles of a substance are moving

Why dose heating increase the speed at which a solution dissolved in water
