Question

a container with a volume of 2.5L contains air at a pressure of 0.5 atm. if the volume is reduced to 1.5L at constant temperature, what will be the resulting pressure of the air inside

Answer 1

Final pressure of the air inside is 0.83atm

Step-by-step explanation:

Boyle's law is the gas law that relates the change in volume when pressure change at constant temperature and vice versa. The equation is:

P₁V₁ = P₂V₂

Where P is pressure and V is volume of 1, initial state and 2, final state of the gas

Replacing:

P₁ = 0.5atm

V₁ = 2.5L

P₂ = ?

V₂ = 1.5L

P₁V₁ = P₂V₂

0.5atm*2.5L = P₂*1.5L

0.83atm = P₂

Final pressure of the air inside is 0.83atm
