boiling point of liquid hydrogen

When a liquid is heated, the molecules gain more kinetic energy and the temperature starts rising. After it has reached a specific point though heat is being supplied, the temperature becomes steady. At this temperature the energy supplied gets utilized in breaking the inter-mo..

Ammonia (240 K) has a higher boiling point than phosphine (190 K) and then the boiling point increases down the group because of increase in size. In PH 3 and other hydrides, the intermolecular forces are Van der Waals' forces. These van der Waals' forc..

The boiling point of liquid is raised by increasing the pressure and reduced by lowering the pressure. It can be demonstrated by the apparatus shown in figure...

The melting and boiling points of group 14 elements are much higher as compared to those of group 13 elements. Explanation: It is because the atoms of group 14 can form four covalent bonds with each other and, therefore, there are strong binding forces between their atoms in bot..

Aldehydes and Ketones have relatively high boiling point as compared to hydrocarbons of comparable molecular masses. This is because the aldehydes and ketones contain polar carbonyl group and therefore have stronger intermolecular dipole dipole interactions between the opposite..

Amines are polar compounds and have higher boiling points than non-polar compounds such as hydrocarbons of some molecular mass. All amines can form hydrogen bonds as protons acceptors by coordination with the lone pair of electrons on the -N atom. But only primary and..

Boiling point of alcohols are much higher than those of alkenes, halo alkenes or ethers of comparable molecular masses. This is because in alcohols intermolecular hydrogen bonding exists due to which a large amount of energy is required to break these bonds. Phenols ..

The melting and boiling points of elements are determined by the inter-atomic or inter-molecular forces between the constituent particles in the lattice and liquid state respectively. It is difficult to predict the variation in melting and boiling point..

Boiling point of alcohols are much higher than those of alkenes, halo alkenes or ethers of comparable molecular masses. This is because in alcohols intermolecular hydrogen bonding exists due to which a large amount of energy is required to break these bond..
