At room temperature water is liquid and has boiling points $373 \mathrm{K}$ due to hydrogen bonding. Where as ${\mathrm{H}}_2\mathrm{S}$ is gas and it has no hydrogen bonding. Hence boiling point of ${\mathrm{H}}_2\mathrm{S}$ is less than $300 \mathrm{K}$ [Boiling point of ${\mathrm{H}}_2\mathrm{S}$ is $-60$ $°\mathrm{C}$]
