NH3 Has a Higher EN than PH3 and will exhibit Hydrogen bonding. Because of this, NH3 has a stronger bond with PH3 so its boiling point is higher (harder to break bonds, more temperature required).
Ammonia has a higher boiling point then methane because it is a polar molecule, meaning that one part of the molecule has a partial positive charge while the other has a partial negative charge. As a result, ammonia molecules are attracted to each other in a similar manner as magnets are.
Methane, dues to its symmetry, is nonpolar.
NH3 is a polar molecule, so the molecules attract each other like magnets.
CH4 is completely symmetrical, so it is non polar.
Therefore, NH3 has a higher boiling point because it takes more energy to knock its molecules away.
CH3Br is a polar molecules, meaning that one end of the molecule has a partial positive charge wile the other has a partial negative charge. This causes the molecules to be attracted to each other in much the same manner as magnets., making it harder to turn the substance into gas. Methane, by contrast, is nonpolar and so this effect does not apply to it.
CH3Br also has greater molar mass , which gives it stronger "Dispersion" London Forces (inter molecular forces) increasing its boiling point more than the CH4 But this is a relatively minor factor compared with polarity
Ammonia is a strongly polar molecule with a positively charged end and a negatively charged end on each molecule. The creates a strong attractive force between molecules that greatly raised the boiling point. Methane is nonpolar, so the attractive forces between molecules are much weaker.
Both NH3 and HCl exhibit hydrogen bonding as intermolecular forces, whereas CH4 does not. This makes CH4 have a lower boiling point. Since there are 3 hydrogen atoms in NH3 and only 1 in HCl(g), the intermolecular forces would be expected to be greater in NH3 than in HCl.
NH3 is heavier then CH4, and NH3 has hydrogen bonding.
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.
Indeed it can. At the boiling point liquid methane is in equilbrium with gaseous methane, so both exist simultaneously.
The boiling point of ammonia at atmospheric pressure is -33.34oC.
The meaning is at what temperature does ammonia melt at and what temperature does ammonia boil at? for eg. waters melting point is 0 degrees celcius and the boiling point of water is 100 degrees celsius

it doesn't

Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.
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.

Ammonia: -33,34 0C Nitrogen trifluoride: -129 0C
At low pressure the boiling point is lowered and inverse.
If you mean ammonia, the melting point of ammonia is −77.73 °C, and its boiling point is −33.34 °C. (Wikipedia)
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.
