Answer:
38.4L
Explanation:
Given parameters of the ethylene gas:
Initial Volume V₁ = 3200L
Initial pressure P₁ = 3atm
Final Volume V₂ = 250L
Final pressure P₂ = ?
We need information about the unknown final pressure.
Based on the given parameters, we can apply Boyle's law. The law states that "the volume of a fixed mass of a gas is inversely proportional as the pressure changes if temperature is constant".
NB: We assume that the torch provides a constant source of heat.
The law is expressed mathematically as:
P₁V₁ = P₂V₂
Making the unknown P₂ the subject of the equation gives:
P₂ = P₁V₁ / V₂
P₂ = 3200x3/250
P₂ = 9600/250
P₂ = 38.4L
Pressure of the gas = 38.4L
