Water has stronger hydrogen bonds than Methane. More energy is required to break them, hence the difference in boiling point
The bonds between H and O are stronger than the bonds between C and H.
The hydrogen bonds between water molecules accounts for water's relatively high boiling point. Energy must go into breaking the hydrogen bonds before the water can boil.
Metahne does not have a higher boiling point than methane. Fluoromethane, CH3F, has a boiling point of 195K, -78.2C, methane, CH4, has a boiling point of 109K approx -164 C. I make that fluoromethane has a higher temeprature boiling point than methane. This is what you would expect, London dispersion forces will be greater in CH3F as it has more electrons than CH4. CH3F is polar and there will be dipole dipole interactions which will not be present in CH4.

The boiling point is always higher than the melting point.
methanol
The normal boiling point is the boiling point at sea level, or more precisely, at 1 atmosphere pressure. At higher elevations, or at lower atmospheric pressures, the boiling point is lower. At higher atmospheric pressures, the boiling point is higher.
Yes, Boiling point of ammonia, NH3: - 33,34 0C Boiling poit of methane, CH4: - 161,6 0C

Indeed it can. At the boiling point liquid methane is in equilbrium with gaseous methane, so both exist simultaneously.
At low pressure the boiling point is lowered and inverse.
Because of the hydrogen bonds in HCl and it's polarity. High polarity = high boiling point. All alkanes (methane) are nonpolar and have low boiling points. Alcohols and compounds with hydrogen bonding have higher boiling points because hydrogen bonds are very strong. Ask a chemistry teacher if you need a better explanation.
Chlorine has higher boiling point.
Methane has a boiling point of −161 °C at a pressure of one atmosphere. For the source and more detailed information concerning this subject, click on the related links section indicated below.
Water because water has the highest boiling point, < anything.
At one atmosphere of pressure (14.7 psia) water boils at 212o F degrees. This can be significantly higher or lower depending on the pressure.
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
Ammonia (NH3) has hydrogen bonding intermolecular forces, whereas methane (CH4) does not. In addition, ammonia is polar, and so also has dipole-dipole forces and methane does not. Thus, it takes more energy (higher temperature) to boil and melt ammonia than it does methane.
