effects of boiling point on the solids

When salt is added to boiling water the temperature of boiling water is raised above 100 o C. This is because the salt absorbs heat energy from the water for dissolving in it and its average kinetic energy decreases. When gases dissolve in water it lowers the boiling ..

Melting Points and Boiling Points - 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, the..

A liquid may be made to boil at any desired temperature by changing the external pressure. For example, a liquid may be made to boil at higher temperature by increasing the pressure on its surface, as is done in a pressure cooker. It may be made to boil at a lower tem..

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-molecular fo..

Carboxylic acids have higher boiling point than aldehydes and ketones and even alcohols of comparable masses. This is due to more extensive association of carboxylic acid molecules through intermolecular hydrogen bonding...

The boiling points of alkenes gradually increase with an increase in the molecular mass (or chain length). This indicates that inter-molecular attractions become stronger with an increase in the size of the molecule. Branched chain alkenes have lower boiling poin..

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..

Pure nitric acid boils at 86 o C. However it undergoes partial decomposition at this temperatur..

The melting points and boiling points decrease on moving down the group. However, the decrease in melting points is not as regular as in boiling points..

Metals have high melting and boiling point. Tungsten has the highest melting point where as silver has low boiling point. Sodium and potassium have low melting points..
