AIM
To determine the melting point of ice and the boiling point of water.
OBJECTIVE A
To determine the melting point of ice.
MATERIALS REQUIRED
Ice cubes, filter paper, beaker, wire gauze, tripod stand, burner, thermometer, stirrer, clamp stand.
THEORY
Ice is the solid form of H20. Its melting point is 0 °C i.e., the forces of interaction between the molecules in the solid form of H20 can be broken down at 0 °C and solid H20 gets converted into liquid water.
PROCEDURE
Take some ice cubes. Dry them using the filter paper and put them quickly in a beaker.Place the beaker on a wire gauze kept over a tripod stand.Suspend a thermometer, into the ice cubes, with the help of a clamp stand.
Heat the ice cubes and stir continuously for uniform heating.Note the temperature (t1) when ice starts melting.Heat continuously till ice melts completely. Note this temperature (t2).Record your observations in the table.
