H₂O is liquid and H₂S is a gas because-

Oxygen forms stronger hydrogen bond thansulphur

Oxygen is less electronegative thansulphu

Atomic radius of oxygen is less than that ofsulphur

Atomic radius of oxygen is greater than that ofsulphur

In H2?O there is hydrogen bonding because oxygen has a high electronegativity.

So, the hydrogen atoms from other molecules of water form a hydrogen bonds with oxygen resulting in intermolecular hydrogen bonding.

Therefore at room temperature, H2?O is a liquid and H2?S is a gas.
