Tbh I would pick A because the liquid* decreases. B doesn’t increase
A compound has to be chemically bonded, however, air is not chemically bonded.
This can be proven by freezing air. By freezing air, it yields different liquids at different temperature. Liquid nitrogen has a different boiling point than liquid oxygen.
If air was a compound, they would all have a single boiling point and a single freezing point.
Hope this helps :)
Answer:
This is because an increase in temperature increases the movement of molecules/particles of reactants which encourages collision and subsequently, reaction.
