Small ice cubes are taken in a Funnel. Funnel is fixed to a stand as shown in Figure. Thermometer bulb is kept in the funnel such that it is surrounded by ice cubes, keep a glass bottle below the funnel. Ice begins to melt utilizing the heat of the surrounding air. Water thus formed drops out of the funnel. After 10 minutes note down the level of mercury in the thermometer and take the reading which shows the melting point of ice.
