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.
- 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.
Note: Click on the ‘HELP’ button to see the instructions.
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)
The melting point of ice =__________°C
- The bulb of the thermometer should be kept surrounded with ice cubes.
- Ice should be stirred regularly to keep a uniform temperature throughout.
- Note temperature by keeping your eyes in line with the level of mercury.
