Answer 2

Answer:

Determination of boiling point of water:

Procedure:

• 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.

Observation:

• You will observe a steady stream of bubbles at 100°C .
• This temperature is the boiling point of water.

(you will also observed that the temperature remain constant at 100°C until whole water is converted into steam . It is because the heat energy is being used in overcoming the forces of attraction between the particles of liquids . )
