Answer 1

analyze the problem	initial condition	final condition	known	predict
pressure	20 atm	3.0 atm	decreases
volume	1.0 L			increases

Now, pressure is inversely proportional to volume at constant temperature

so, P $\propto$$\frac{1}{V}$

or, P₁V₁ = P₂V₂

or, 20$\times$ 1.0 = 3.0 $\times$ V₂

or, V₂ = 6.67 L

hence final volume of helium = 6.67 L.
