EVAPORATION AND BOILING

Post author By Bolaji .G

Chemistry

EVAPORATION AND BOILING (LIQUID TO GAS) On heating particles gain kinetic energy and move faster. In evaporation and boiling the highest kinetic energy molecules can ‘escape’ from the attractive forces of the other liquid particles. The particles lose any order and become completely free to form a gas or vapour. Energy is needed to overcome […]

METHODS OF SEPARATING MIXTURES

Post author By Bolaji .G

Chemistry

METHODS OF SEPARATING MIXTURES Mixtures can be separated from applying the following methods: (A) DECANTATION Sediments can be separated from a liquid by pouring out the liquid. This process is called decantation. Experiment Put some sand in a beaker. Add about 200cm3 of water. Allow sand to settle. Pour off water carefully into another beaker. […]
