Melting Point of Ice

 

Materials Required:

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.

Simulator Procedure:

  • You can select different pressures from ‘Select the pressure’ drop down list. (The zoomed view of the thermometer can be seen on the right side.)
  • To put ice cubes into the beaker, drag the watch glass towards the beaker.
  • You can see that the temperature level on the thermometer suddenly drops.
  • To turn on the burner, click on the knob of the burner.
  • To stir the ice cubes in the beaker, click on the stirrer.
  • When ice starts melting, you can see the temperature t1°C, on the left hand side box.
  • Continue stirring with the stirrer.
  • When ice has completely melted, you can see the temperature t2°C on the left hand side box.
  • You can calculate the melting point of ice using the equation given under ‘Result’ .
  • You can verify your result by entering the value on the check box under ‘Result’ .
  • Click on the ‘Reset’ button to redo the experiment.

Observations:

Record your observations in the table given below: 

Temperature when the ice Melting point of ice
Starts melting   t1 (°C) Completely melted   t2 (°C) (t1 + t2)/2 (°C)
     

Inference:

The melting point of ice =__________°C

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.
