Making Ice You place 0.410 kg of cold water inside a freezer that has a constant temperature of 0 °C. The water eventually freezes and becomes ice at 0 °C. (a) What is the change in entropy of the water as it turns into ice? (See Table 17-4 for the appropriate latent heat) (b) If the coefficient of performance of the freezer is 4.50, how much heat does the freezer exhaust into your kitchen as a result of freezing the water? (c) If your kitchen temperature is 22 °C, what is the increase in entropy of your kitchen? (d) What is the change in entropy of the universe during the freezing process?

1.
Using the metric (top) scale only, what units are being used for the long lines
with the numbers? Hint: Remember that 2.54 cm = 1 in.
2.
What are the units of the small lines?
3. How many decimal places should be recorded using this tool?
4. What is the length of the red line? Note: Make sure to use the correct units
and decimal places.
5. Now observe your ruler. What metric units are used on your ruler?
6. How many decimal places should you record when using your ruler?
7.
Measure a box, book, coin and can and fill out the data table below. Make
sure to use units and the correct number of decimal places for your ruler.
