Answer the following questions.

(a) What will you do to find out the boiling point of water?

(b) What changes do you see in the appearance of a candle after you have lit it?

(c) Can a solid and a solvent be separated from their solution by distillation?

(a) The boiling point of water can be found by boiling the water. When the water is boiling, the temperature increases rapidly but after some time the increase in temperature stops. Now the thermometer can be placed to see the boiling point. The boiling point of water is 100℃.

(b) When we lit the candle it starts melting as it has a low melting point. The heat of candle melts the nearby wax. The liquid wax starts dripping and the height of the candle starts decreasing.

(c) No the solid and a solvent cannot be separated by distillation. It can be separated by the process called sedimentation and decantation or loading or solvent extraction method.
