differentiate between distillation and fractional distillation
Answers
Answer:
Distillation is the process of heating a liquid to form vapour and then cooling the vapour to get back liquid.
Liquid -------------------》vapours

eg . to separate the salt water mixture
fractional distillation is a process of separating two or more miscible liquid by distillation, the distillate being collected in fractions boiling in different temperatures.
eg . to separate a mixture of alcohol and water
Answer:
Distillation is a separation technique that is used to purify a liquid or a mixture of liquids by heating followed by cooling. When a mixture of liquids is heated, the components which have different boiling points go into gaseous phase at different instances. Condensation of the vapour allows it to be liquefied and thus, different components can be separated. There are several different distillation techniques adapted according to the composition of the liquid mixture. These are simple distillation, fractional distillation and steam distillation. The main difference between fractional distillation and simple distillation is that simple distillation separate liquids with boiling point gaps of at least 50 degrees whereas fractional distillation separates liquids with closer boiling points.
