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.

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.

Boiling point of ethanol is higher than its isomer methane due to the presence of hydrogen bond in ethanol

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 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.

The boiling point of Methane is 83F

Water has stronger hydrogen bonds than Methane. More energy is required to break them, hence the difference in boiling point

Because octane has more carbons, and the more carbons you have the higher the melting point. also octane is a gas that is very close to nonane (which is the first liquid) and that would mean it has a larger boiling point that methane (which is a gas that is the first one CH4). that is why octane has a larger boiling point that methane. Also, you can also figure it out the boiling points of each and look at the differences.

The intermolecular forces in neon are weaker than those in methane

The boiling point of methane is NOT higher, but lower than of propane (about 119 degrees lower), as can be seen from the table below:Methane: Bp. −161 °C, 112 KPropane: Bp. -42.1, 231.1 K

because the ammonia has been filtered through the cat's kidneys removing all the properties within the ammonia that would make the boiling point higher than water

Both compounds are straight chained alkanes. (General formula CnH2n-2) The general rule is the bigger the molecule in a group of similar compounds the higher boiling point it has. Methane is C1, butane is C4 - much bigger.

The boiling point of methane is -161 degrees Celsius or -278.5 degrees Fahrenheit

The boiling point of ammonia is −33.34 °C (which is 240 K or -28 °F).

Methane is gas derived from liquid methane.

This is because methane is more stable or happier than ethane. It has a shorter carbon chain and less branching making it the harder one to boil.

The boiling point of ammonia at atmospheric pressure is -33.34oC.

The boiling point of water is 100 0C at 760 mm col. Hg. The boiling point of methane is -164 0C.

Indeed it can. At the boiling point liquid methane is in equilbrium with gaseous methane, so both exist simultaneously.

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

Because the hydrogen bonding in HF is much stronger than the intermolecular bonding in ammonia.

Ammonia: -33,34 0C Nitrogen trifluoride: -129 0C

At low pressure the boiling point is lowered and inverse.

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.
