A gas at a pressure of 2.0 atm is in a closed container. Indicate the changes (if any) in its volume when the pressure undergoes the following changes at constant temperature and constant amount of gas.

When there is a change in the pressure (P) at constant temperature (T) and amount of gas (n), we can find the change in the volume (V) using Boyle's law.

P₁.V₁ = P₂.V₂

where,

1 refer to the initial state

2 refer to the final state

a) The pressure drops to 0.40 atm.

P₁.V₁ = P₂.V₂

(2.0 atm) . V₁ = (0.40 atm) . V₂

V₂ = 5 . V₁

The volume increases.

b) The pressure increases to 6.0 atm.

P₁.V₁ = P₂.V₂

(2.0 atm) . V₁ = (6.0 atm) . V₂

V₂ = 0.33 . V₁

The volume decreases.

c) The pressure remains at 2.0 atm.

P₁.V₁ = P₂.V₂

(2.0 atm) . V₁ = (2.0 atm) . V₂

V₂ = V₁

The volume does not change.
