In the same conditions of course.

As a general rule, the properties of an element are often *very* different from the properties of its compounds, just as compounds are very different from each other. We drink H2O to keep ourselves alive, but drinking H2O2 would be harmful or fatal – that difference of one extra hydrogen atom bonded completely changes the properties of the compound.
In the case of water, the thing that makes it a liquid at room temperature is called *hydrogen bonds*. In each water molecule, one side of the molecule has a slight negative charge (near the O) and the other sides (near the H’s) have a slightly positive charge. This attracts water molecules to each other slightly – not enough for a true chemical bond, but enough to change the way that they interact. With enough heat energy, these small bonds won’t hold, and water will boil into steam. But at room temperature, they’re strong enough to give water a liquid state, bonded more closely together. A very similar molecule, H2S, has a much weaker negative charge on the S side, and so it winds up being a gas at room temperature, because the forces aren’t strong enough to hold it in a liquid state, like H2O.
