How does the volume occupied by a gas vary with (i) pressure, and (ii) temperature?

Answer 1

Owen Ambrose

If we assume ideality, then #V=(nRT)/P#

Thus, volume increases with rising temperature and varies inversely with pressure.

(i) According to Boyle's law, the volume of a gas is inversely proportional to its pressure when temperature and the number of moles of gas are constant. This means as pressure increases, volume decreases, and vice versa.

(ii) According to Charles's law, the volume of a gas is directly proportional to its temperature when pressure and the number of moles of gas are constant. This means as temperature increases, volume increases, and vice versa.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
