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.
Determination of melting point of ice:
▪ Take crushed ice in a beaker and insert a thermometer in the beaker by hanging it from the clamp of the stand in such ay that the bulb of the thermometer is completely inside the ice.
▪ Wait for some time and keep recording the temperature after small intervals of time.
▪ Note down the temperature when ice just starts melting.
▪ Let the bulb of the thermometer remain in mixture of ice and water for some more time and keep recording the temperature. This temperature is the melting point of ice.
