the questions of effects of boiling point

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...

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 ..

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..

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..
