1. Create an Excel worksheet that will convert inches to one of the following metric units: millimeters, centimeters, meters, or kilometers, depending on the magnitude of the given value. (Note: 1 inch = 2.54 centimeters.) Use the following rules to determine which metric unit will be shown: (i) If the given value is less than 1 inch, convert to millimeters. (ii) If the given value is greater than or equal to 1 inch but less than 100 inches, convert to centimeters. (iii) If the given value is greater than or equal to 100 inches but less than 10,000 inches, convert to meters. (iv) If the given value is greater than or equal to 10,000 inches, convert to kilometers. Use the worksheet to carry out the following conversions: (a) 0.04 inch (b) 32 inches (c) 787 inches (d) 15,500 inches

2. Example 5.1 Creating an X-Y Graph in Excel
The voltage drop across a capacitor varies with time in accordance with the formula 𝑉 = 10 𝑒 −0.5𝑡 where V represents voltage drop, in volts, and t represents time, in seconds. Prepare an x-y graph of the voltage as the time varies from 0 to 10 seconds. Display the data to three-decimal precision using arithmetic coordinates. Label the graph so that it is legible and attractive.

3. Example 5.2 Adding Data to an X-Y Graph
Suppose we wish to add two additional data points to the existing data that we have plotted in Example 5.1. The voltage will be calculated as before, using the expression 𝑉 = 10 𝑒 −0.5𝑡 for the values t = 0.5 and t = 12 seconds.

4. Example 5.3 Adding Dependent Variables to an X-Y Graph
Now suppose we wish to add an additional set of voltages to the data that we have plotted in Example 5.1. The new voltage data will apply to a second device. These voltages will be calculated using the expression 𝑉 =8 𝑒 −0.5𝑡 where V represents voltage and t represents time, in seconds.

5. The relationship between pressure, volume, and temperature for many gases can be approximated by the ideal gas law, which is written as 𝑃𝑉 = 𝑅𝑇 where P is the absolute pressure, V is the volume per mole, R is the ideal gas constant ( liter atm/mole K), and T is the absolute temperature. (a) Construct an Excel worksheet containing a table of pressure versus absolute temperature for temperatures ranging from 0 to 800 K, and specific volumes of 20, 35, and 50 liters/mole. Note that the worksheet should contain four columns. The values of the absolute temperature should be placed in the first column, and the second column should contain the corresponding pressure values for a specific volume of 20 liters/mole. The third and fourth columns should contain the pressure values for specific volumes of 35 and 50 liters/mole, respectively. (b) Plot all of the data (i.e., all three pressure versus temperature curves) on the same x-y graph. Edit the graph so that it is legible and attractive. Include a legend, indicating the specific volume associated with each curve.
