4. Allow the water to continue boiling for approximately 5 minutes. After 5 minutes, measure the temperature with the thermometer and record the measurement to the correct level of precision. Record the measurement in Data Table 2.

4. Allow the water to continue boiling for approximately 5 minutes. After 5 minutes, measure the temperature with the thermometer and record the measurement to the correct level of precision. Record the measurement in Data Table 2.

5. Once you are done with this experiment, carefully remove the measuring cup from the microwave using a potholder and set aside to cool.

6. Turn on the tap water to cold. Let the water run as cold as possible for approximately 15 seconds.

7. Fill the cup (plastic or drinking) approximately half-full with cold tap water.

8. Measure the temperature of the cold tap water with the thermometer and record the measurement to the correct level of precision. Record the measurement in Data Table 2.

9. Add a handful of ice cubes to the cup of cold tap water and allow them to sit in the cold water for approximately 1 minute.

10. After 1 minute stir the ice water with the thermometer.

11. the temperature of the ice water after 1 minute with the thermometer and record the measurement to the correct level of precision. Record the measurement in Data Table 2.

12. Allow the ice to remain in the water for an additional 4 minutes.

13. After the additional 4 minutes stir the ice water with the thermometer.

14. the temperature of the ice water after 4 minutes with the thermometer and record the measurement to the correct level of precision. Record the measurement in Data Table 2.

15. Convert the temperature measurements for each of the 6 water samples from °F to °C and K. Record the converted temperatures in Data Table 2.

III. Mass Measurements (Conversions)

1. Review the different object(s) listed in Data Table 3.

1. Use the masses provided for each of the object(s) in grams and record in Data Table 3.

2. Decide which pennies (before or after 1982) you are using for your calculations and stick with the choice throughout the conversions and indicate your choice.
