What determines the boiling point of a substance is how strongly the molecules of the substance attracts each other. With this in mind, and since nitrogen is a more electronegative molecule, the more exposed nitrogen is, the more polar the molecule would be and this polarity would cause slightly more ionic interactions between molecules, causing them to attract each other more.
Trimethylamine has H-H interactions which are fairly weak and can be neglected. Since the structure of the molecule is like a pyramid, there is a dipole but compared to n-propylamine, this dipole is not as strong, since the nitrogen is more exposed.
Basically, because n-propylamine can act as both a H-bond donor AND a H-bond acceptor (while trimethylamine only acts as a H-bond acceptor) this makes n-propylamine have a higher boiling point.
Because due to three methylen groups, trimethylamine molecules can easily fly from the liquid. Methanol has only one methylene group and N and OH groups can not fly.
Chlorine has higher boiling point.
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.
Heptane - longer the chain, higher the boiling point. Least amount of branches, higher the boiling point.
Sea water has higher boiling point,as it contains sodium chloride
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.

The boiling point is higher.
Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.
The boiling point is always higher than the melting point.
iodine is having higher boiling point
Heptane - longer the chain, higher the boiling point. Least amount of branches, higher the boiling point.
Higher then the boiling point of the solvent.
Sea water has higher boiling point,as it contains sodium chloride
The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.
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.
The magnesium chloride solution has a higher boiling point.
