Heat 1 Experiments 1.2 Experiment 1 Heating and cooling water Fill the Erlenmeyer flask to the brim with (coloured) water. The rubber stop- per is then inserted in the flask. The glass tube is inserted in the hole in the stopper, which causes the water to rise in the glass tube. -
Page 7: Experiment 3: How Does A Thermometer Function
Heat 1.3 Experiment 3 How does a thermometer function? The thermometer without graduation is alternately dipped into the beakers containing water at different temperatures. The thermometer functions in the same way as the equipment set up in experiments 1 and 2: when it is heated the alcohol in the thermometer expands, and it contracts as it cools. -

Heat Compare with the thermometer with Celsius scale, which shows 100 equal divisions between the marked two points (0 °C to 100 °C). Materials: 1 thermometer without graduation (4) 1 thermometer -3 °C to 103 °C (5) 1 plastic beaker (9) 1 red peg (12) 1 blue peg (12) 1 immersion heater (13) -
Page 9: Experiment 8: Water Evaporates, Vaporizes Too
Heat 1.8 Experiment 8 Water evaporates, vaporizes too The Erlenmeyer flask is set up as in experiment 7 but now a drop of water is placed on its base. In this case too, the drop of water evaporates after a while even though this happens slower than it did in experiment 7. -
Page 10: Experiment 11: What Happens When Steam Cools Down
Heat 1.11 Experiment 11 (Demonstration) What happens when steam cools down? Fill a heat-resistant beaker with water and bring the water to the boiling- point with an immersion heater. Now hold the plastic container filled with ice cubes over the steam. The water boils. -
Page 11: Experiment 13: How Water Particles Unite
Heat 1.13 Experiment 13 How water particles unite Fill the atomizer with water. Spray the water onto a window or blackboard from a distance of approximately 30 cm. The tiny particles from the atom- izer form a barely visible water cloud, but on the sprayed surface they unite after a while and form drops of increasing size. - Page 12 Heat Some selected temperatures in degrees Celsius (°C) 6000 surface of the sun 2500 filaments in a lamp 1535 iron melts 1063 gold melts 950 to 1200 flame of gas burner match flame mercury boils lead melts electrical soldering iron smoothing iron (linen setting) water boils alcohol boils...
