Investigating State Changes

Aim:

To observe water as it changes state from solid to liquid and then to a gas.

Equipment:

- 250ml beaker
- Thermometer
- Bunsen burner
- heatproof mat
- Tripod
- Gauze mat
- stopwatch
- retort stand
- clamp
- ice cubes

Method:

1. Collect enough ice so that your beaker is half full and place the thermometer into it while you set up the rest of the equipment.
2. Set up the retort stand and clamp alongside the tripod and gauze mat.
3. Place the beaker of ice on the gauze mat and gently clamp the thermometer so that it is held upright and the scale is easy to see. The bottom of your thermometer should be low enough to still be covered by water when the ice melts, but not touching the bottom of the beaker.
4. Record the initial temperature of the ice in the data table below.
5. Light the bunsen burner and start timing with the stopwatch.
6. Measure and record the temperature every minute.
7. Continue measuring and recording the temperature until the water has been boiling for 2-3 minutes.

Results:

0 - 3
1 - 6
2 - 19
3 - 29
4 - 37
5 - 57

Observing Diffusion

Aim:

To observe diffusion in a liquid.

Equipment:

- Petri dish
- water
-  tweezers
- a crystal of potassium permanganate

Method:

1. Half fill your petri dish with cold tap water.
2. Place the petri dish on your workbench and allow the water to become settled.
3. Using the tweezers, place a single crystal of potassium permanganate in the center of the petri dish.
4. Observe for 5 minutes.
5. Repeat the experiment using hot water.
