Determination of boiling point of water:
In a beaker take some water and insert a thermometer in it with the help of a clamp.Put the beaker on a tripod stand and heat the apparatus with the help of kerosene burner slowly.Observe what happens to water.You will observe a steady stream of bubbles. This temperature is the boiling point of water.
