$PH_3$ forms bubbles when passed slowly in water but $NH_3$ dissolves. Explain why?

(N/A) $NH_3$ is capable of forming hydrogen bonds with water molecules due to the high electronegativity and small size of the nitrogen atom,which makes it highly soluble in water.
In contrast,$PH_3$ (phosphine) has a much lower electronegativity and larger atomic size,preventing it from forming hydrogen bonds with water molecules.
Consequently,$PH_3$ is only sparingly soluble in water and escapes as bubbles.
