The Procedure:

Real Lab Procedure:

  • Take some ice cubes and dry them using a filter paper and quickly put them in a beaker.
  • Place the beaker over a wire gauze kept over a tripod stand.
  • Suspend a thermometer (temperature range -10 to 110°C) with the help of a clamp stand so that its bulb remains in the middle of the ice cubes.
  • Ice cubes are moderately heated by a gas burner and stirred continuously using a glass rod.
  • Note the temperature (t1) when the ice starts melting.
  • Continue heating the ice.
  • Note the temperature (t2) when the ice has melted completely.
  • Record your observations in tabular form.

 

Precautions:

  1. The bulb of the thermometer should be kept surrounded with ice cubes.
  2. Ice should be stirred regularly to keep a uniform temperature throughout.
  3. Note temperature by keeping your eyes in line with the level of mercury.
