Question 74
Experiment 2
You will need: the apparatus shown in the diagram – make sure that the water is really cold, a lamp.
Method
1 Read the temperature on the thermometer, and the level of the water in the glass tubing. Record them in a results chart.
2 Place a lamp close to the conical flask and switch it on. The lamp will gently warm the water in the flask.
3 Approximately every five minutes (the exact timing does not matter), record the temperature and the level of the water in the glass tubing. Keep going until you have at least 10 readings.
