<h3>Answer:</h3>
The pressure will decrease by half.
<h3>Explanation:</h3>
Data Given:
P₁ = 101.3 kPa
V₁ = X
V₂ = 2X
P₂ = ??
Let us suppose the initial volume is 5 L and the final volume when doubled is 10 L. Then According to Boyle's Law, " The Volume of a given mass of gas at constant temperature is inversely proportional to the applied Pressure". Mathematically the initial and final states of gas are given as,
P₁ V₁ = P₂ V₂ ----------- (1)
Solving equation 1 for P₂,
P₂ = P₁ V₁ ÷ V₂
Putting values,
P₂ = (101.3 kPa × 5 L) ÷ 10 L
P₂ = 50.65 kPa
<h3>Result:
</h3>
As the volume is doubled, the pressure is decreased from 101.3 kPa to 50.65 kPa or it has decreased by half.
