Answer:
Step-by-step explanation:
The question relates to Boyle's law which states that at constant temperature the volume of given mass of gas is inversely proportional to the pressure
V = K/p
PV = K
P₁V₁ = P₂V₂ where P₁ = P atm ( pressure) P₂ = 3P
then P V₁ = 3P V₂
V₂ = V₁ / 3 so the volume is reduced to one-third its original volume.
