H2s hydrogen sulfide is a gas because at room temperature the forces and interactions between the molecules of hydrogen sulfide are very weak.
Why water is a liquid at room temperature but hydrogen sulphide is a gas.
The water molecule has a stronger dipole a.

Thus due to stronger intermolecular forces in water water will be a liquid and hydrogen sulfide having much weaker intermolecular forces will therefore exist as a gas under standard atmospheric.
Its because of hydrogen bonding that occurs between the h and o of adjacent water molecules.
The water molecule has a stronger dipole a negatively and positively charged end to the individual molecule so these negative and positive ends continually attract each other like magnets of opposite poles creating more cohesion between the molecules of water explaining the liquid phase.
So lesser energy is required to overcome the forces of interaction between the hydrogen sulphide molecules than those between water molecules.

This energy is available at room temperature and hence hydrogen sulphide is a gas while water is still a liquid.
