1. Measure the cylinder that your teacher gave you using a triple balance scale and round to the nearest tenths place. 2. Heat about 350mL of water in a 400mL beaker until it is boiling gently. 3. While the water is heating, measure the mass of the metal cylinder to the nearest 0.01 g and record the measurement. 4. While the cylinder is heating, measure approximately 100 mL of water in a graduated cylinder. Record the mass of the water based on the volume of the water you measured and related to the density of water to one decimal place. Then pour the water into a plastic-foam cup. 5. While the cylinder is heating, measure approximately 100 mL of water in a graduated cylinder. Record the mass of the water to one decimal place. Then pour the water into a plastic-foam cup. 6. Measure and record the temperature of the water in the plastic-foam cup and of the water in the boiling bath. This temperature should be recorded to one decimal place. 7. Create a hole on another foam cup on the center bottom.
8. Remove the test tube from the boiling water and quickly pour the cylinder into the water-filled, plastic-foam cup. 9. Place the cup with the hole upside down on the other foam cup filled with water.
10. Place a thermometer into the hole. This temperature should be recorded to one decimal place. 8. Repeat steps 1 – 6 for a second trial. Pour the water off and return the cylinder to your teacher.
