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.
Yes, Boiling point of ammonia, NH3: - 33,34 0C Boiling poit of methane, CH4: - 161,6 0C
Methane consists of separate CH4 molecules that can move freely and are only weakly attracted to one another. Diamond consists of a covalent network in which each carbon atom is strongly bonded to its neighbors.
Melting and boiling points are higher when intermolecular forces (such as hydrogen bonding, dipole-dipole interactions, or London dispersion forces) are stronger. These forces hold molecules together, so more energy is required to overcome them and change the state of the substance. Conversely, weaker intermolecular forces result in lower melting and boiling points.
IMF (intermolecular forces) affect the boiling and melting points of a substance by influencing the strength of the bonds between molecules. Stronger IMFs lead to higher boiling and melting points because more energy is required to overcome these forces. Weaker IMFs result in lower boiling and melting points as less energy is needed to break the intermolecular interactions.
The boiling point is typically higher than the melting point for a substance. The boiling point is the temperature at which a substance transitions from a liquid to a gas, while the melting point is the temperature at which a substance transitions from a solid to a liquid.

it doesn't
The boiling point is always higher than the melting 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.

Ethanol (C2H5OH) has a higher boiling point than methane (CH4) because it has stronger intermolecular forces, specifically hydrogen bonding, which requires more energy to overcome and boil. This results in a higher boiling point for ethanol compared to methane.
Yes.
well acuttaly a boiling point is higher because the boiling point is at 100 degrees and like so a melting point is a 0 degrees and a boiling point the particles spread out quicker but the melting point the particles are a strong bond so cannot be squahsed and are at a lower rate of temprrature/heat
