Please answer the following questions:

Question #1: PRE-LABORATORY ASSIGNMENT

Plot the dataprovided on the attached graph paper or plot using excel or another graphing program.

Plot Temperature of water on the X-axis and Density of Water on the Y-axis.

Make sure you use at least 70 % of the graph paper and draw the beststraight linethrough the plotted points. DO NOT JOIN the points!!

Remember to label both axes and have a title for the graph.

Here is an example of what the graph should look like: Density of Water against Temperature of Water

The correct reading is 1.67 cm. The first 2 digits 1.67 are known exactly. The last digit 1.67 is uncertain. You may have instead estimated it as 1.68 cm. 1. Let's measure the length of the index card. (Click) Let us zoom in to read the scale. (Click) Make sure to read the ruler to the correct number of decimal places and write the number of sig figs for measurement. 2. Let's measure the width of the index card. (Click) Let us zoom in to read the scale. (Click)Make sure read the ruler to the correct number of decimal places and write the number of sig figs for measurement. 3. Calculate the Area and report unrounded value. 4. Take unrounded value and covert from cm to inch using the provided conversion factor. Make sure your answer is reasonable (Hint: We are using a 3" x 5" index card) and that it has the right number of significant figures.
