1.To observe and explain changes in volume during a phase change.

1.Add water to the test tube until it is about 1 cm deep. Fasten a balloon over the end of the test tube with a rubber band. Hold the test tube upright with a test tube holder and heat it gently with a bunsen burner. Record what happens in Table I.

2.When the balloon is fairly full hold the tube upright and observe how much water is left . Record the results in Table I. Allow the test tube to cool in the room. Record what happens in Table I.

4.Observe a Ball and Ring Apparatus. Attempt to put the ball through the ring. Record what happens in Table I.

5.Heat the ball for several minutes in a bunsen burner flame. Again attempt to pull the ball through the ring. Record what happens in Table I.

6.Place a stopper holding a glass tube with attached balloon into an empty 250 mL Erlenmeyer flask. Gently heat the air in the flask. Record what happens in Table I.

7.Obtain a test tube containing some wax. Obtain a 400 mL beaker about three-quarters full of hot tap water. Using a test tube holder or utility clamp and support stand position the test tube containing the wax in the hot water so that the wax is almost below the water line but the test tube does not touch the bottom of the beaker. Heat the water in the beaker on the hot plate. Record what happens in Table I.

9.Place the test tube containing the wax in a 400 mL beaker of cold water. When the liquid wax has become completely frozen, take it out of the beaker and compare the level of the wax to what it was in the liquid phase after heating. Record the results in Table I.

10.Examine a Stoekle tube containing some coloured glass beads and liquid mercury metal. Gently heat the bottom of the tube with a bunsen burner. Record what happens in Table I.

11.Now heat the Stoekle tube more strongly and record what happens in Table I.

12.Obtain four large textbooks and a Boyle's Law Apparatus secured by a utility clamp and a support stand. Only if necessary, remove the red cap on the bottom of the cylinder and pull the piston up to the top marker to fill the cylinder with air. Replace the red cap securely. Record the volume in mL in Table II.

13.One at a time progressively add large textbooks to the wooden support on the top of the cylinder. Always support the books with two hands but BUT DO NOT PUSH DOWN ! Again record the volume in Table II after each book is added. Be prepared to graph the results.

15.Now obtain a Boyle's Law Apparatus filled with water. Only if necessary remove the red cap and use the piston to draw water from a beaker into the cylinder. Be certain that all air is removed from the cylinder. Pull the piston to the top marker and replace the red cap securely. Record the volume in mL in Table II.

16.Repeat Procedures #13 and 14. Record the volumes in Table II. Be prepared to graph the results.

17.Observe any object in the solid phase. Describe its volume and shape in Table I.

18.Using an eye dropper place a single drop of liquid water on a glass plate. Carefully observe its shape and appearance. Record your observations in Table I.

19.Carefully observe the shape and appearance of the mercury in the bottom of the Stoekle Tube used in Part V. Record your observations in Table I.

20.Using a small beaker half-fill a petri dish with water. Carefully attempt to float a needle on the water. Subsequently tap the petri dish gently. Record your observations in Table I.

21.Dip a stirring rod into the water and draw it out very slowly. Carefully observe the water. Record your observations in Table I.

22.Using a small beaker half-fill another petri dish with water and add some food colouring. Holds the open end of a capillary tube in the water for about 15 seconds. Record what happens in Table I.

23.Place a bar magnet in a cradle hung from a utility clamp on a support stand. Bring the North end of another magnet near the South end of the cradled magnet. Repeat but now bring the North end of the other magnet near the North end of the cradled magnet. In each case describe the behaviour of the magnets in Table I.

24.Hold onto a pen as an example of a solid. Let go of it. Record what happens in Table I.

25.Vigorously but carefully rub a vinyl strip with a wool cloth to give it a static electrical charge. Quickly bring the charged vinyl strip near a pile of small pieces of paper in a petri dish. Record what happens in Table I.

26.Open the bottle of perfume. Stand back a few steps and record in Table I how long it takes to smell the perfume odour.

1.Write the following: "Refer to Table I". Record all observations as described in the Procedure sections I-V and VII-IX in Table I.

2.Write the following: "Refer to Table II". Record data for volumes of air and water being compressed by large textbooks.

3.Write the following: "Refer to Graph I". Plot one graph of "Volume of Material vs Number of Books" for both air and water in the cylinder. The graph should have two clearly labeled smooth curves both on the same graph.

3.State from the experiments in Parts I and IV one specific example each to demonstrate that:

7.With reference to your Graph I: (Show work in dotted lines on the graph)

8.State from the experiments in Parts I-III one specific example each to demonstrate that:

10.State from the experiments in Part VII one specific example each to demonstrate that:

11.How does the "Particle Model of Matter" explain why water particles are pulled up the capillary tube in Part VII ?

12.What are the three types of energy forces that appear to attract matter and are therefore responsible for holding particles of matter together ? State from the experiments in Part VIII one specific example each to demonstrate the action of these three forces. (three answers)

13.In the Stoekle Tube in Part V:
