Yes, Boiling point of ammonia, NH3: - 33,34 0C Boiling poit of methane, CH4: - 161,6 0C
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.
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.
For the same reason that water isn't a gas. Oxygen is highly electronegative and the hydrogen bonding present in water and methanol raises the intermolecular attractive forces and results in a higher boiling point.
Graphite has not a boiling point.
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.

it doesn't

Water is polar and is strongly hydrogen bonded.
No, at their boiling points liquid nitrogen is colder than liquid methane.

The boiling point is always higher than the melting point.
iodine is having higher boiling point

Water boils at a higher temperature than methane because water is a polar compound. Each molecule is held together chemically. Each molecule is held to other molecules by hydrogen bonding. With Methane, it is every molecule for itself.
Graphite has not a boiling point.
