Oxygen (O) is more electronegative than sulfur (S). This means that H2O more polar than H2S.
This means that the forces of attraction between H2O molecules is grater than that in H2S molecules, making it harder to separate them from one another to turn it into a gas.
this is because h2 and o2, non polar molecules have only london forces actng upon them....and this london force is the weakest out of all three intermolecular forces whereas h20 has 2 hydrogen bonds present (stronger IMF) since h2o has stronger attrction to each other they will be closer, so its natural that it would be liquid in room temperatature
Although hydrogen sulphide has a greater molecular mass than water, water is a liquid at room temperature while carbon dioxide is a gas because of the strong intermolecular forces that hold water.
The presence of hydrogen bonding in water, results in more molecules per unit volume. Hence H2O is liquid. No such hydrogen bonding is seen in H2S.
This is because in H20 there is a hydrogen bond whereas in H2S the hydrogen is attracted by very weak van der waals forces

That's correct, unless you've got an abnormally hot or cold room.
If you're asking WHY, it's because of strong hydrogen bonding in the case of water.
H2O have strong Hydrogen bonds.H2S have dipole-dipole bonds,weaker than H bonds.
Due to hydrogen bonding in water
earth is the only planet where the same substance can exist in gaseous , liquid , and solid form
Hydrogen probably cannot exist for a long time on Mars. As you suggest this is because of the planet's fairly low gravity and escape velocity. It's easier for a very light atom or molecule, such as hydrogen, to reach the planet's escape velocity, caused by collisions in the atmosphere.
NH4 is an ion. It does not exist under normal conditions. It may exist in combined state as Ammonium Chloride NH4Cl (which is a sublimates and exists only in solid and gaseous state), Ammonium Nitrate NH4NO3, Ammonium Sulphate (NH4)2SO4 which may exist in gaseous state at high temperatures. In case you are talking about Ammonia which is NH3, then yes,it is a gas under normal conditions but becomes a liquid on bubbling through water. (Ammonia solution of varying concentrations), much like Hydrogen Chloride, which on bubbling through water, forms, Hydrochloric acid in varying concentrations.
Gaseous
Because in gaseous state all the atoms are comparable. In natural state some atoms (Elements) exist in solid state some in liquid and some in gaseous state.
earth is the only planet where the same substance can exist in gaseous , liquid , and solid form
Yes
Francium can be solid, liquid or gaseous.
Solid, liquid, gaseous and plasma.
water is the substance
Yes. In fact, there is a specific combination of pressure and temperature where the solid, liquid, and gaseous phases can co-exist. Do some reading on "triple point".Yes.

Any chemical difference exist.
Both the elements exist in gaseous states at room temperatures.
Yes, nitrogen exists in a gaseous form (N2) at at temperatures above its boiling point. It can also exist as a liquid at 77 K.
At the standard temperature and pressure, hydrogen chloride exists as a gas. It does not exist in liquid state, but in aqueous medium along with water as a solvent.
Water exists in liquid, (water); solid, (ice); and gaseous (steam) form.
Hydrogen can exist as a solid, a liquid, a gas, or a plasma, as well as many other states.
