Originally Answered: Why is H2S gas while H2O is liquid? Water exists as a liquid at room temperature with a high boiling point. Sulphur is less electronegative than oxygen, and the S-H bond is much less polar than the O-H bond. read more
So, at room temperature water's molecules are strongly attached to each other through Hydrogen bonding.While the molecules of H2S are weakly attached to each other so they are converted into gaseous state.Hence H20 is a liquid while H2S is gas at room temperature. read more

The real question should be why is H2O a liquid and H2S a gas at room temperature. Water can be heated into a vapor that behaves similar to a gas. Water molecules are polar (shaped like tiny Mickey Mouse hats) which exhibit surface tension where molecules attract each other. read more
