boiling point questions

Vapour pressure measures the tendency for the molecules to escape from liquid to the gas phase. At lower temperatures the vapour pressure of a liquid is much lower than the pressure on the surface of the liquid. When the temperature of the liquid is gradually increased, its vapour pressure also in..

The boiling points of alkyl chlorides, bromides and iodides follow the order RI > RBr > RCl where R is an alkyl group. With the increase in the size of halogen, the magnitude of Van der Waals forces increases and, consequently, the boiling points incre..

Pure sulphuric acid on boiling decomposes to give water and sulphur trioxide. During boiling more sulphur trioxide is lost than water. As a result, the concentration becomes 98.33%. The acid of this concentration forms a constant boiling mixture with the remaining sma..

Sulphur boils at 444.6 o C and gives off light yellowish orange vapo..

Identify the freezing and the boiling points of water in Fahrenheit scale. => 32°F and 212°F or 37°F or 0°F and 100°F or None of the above..

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..

The melting and boiling points of group 14 elements are much higher as compared to those of group 13 element..

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 Hg has low boiling point. Na and K have low melting points..

The melting point and boiling point of boron halides increase with increase in the atomic number of halogen..
