Measurement and Expression of Experimental Data

You are to analyze this data by graphing it$,$ discovering that a direct graph vs$.P$ gives a curved line. Scientists often try manipulating data to give a straight line, and when the data is regraphed as $P$ vs$.\frac{1}{V},$ you will see that a straight line is produced, revealing the nature of Boyle's law $($that pressure and volume are reciprocally related$).$ Further analysis of this straight line will also reveal the atmospheric pressure at which the measurement is made. Since

$P_{\text{t}\text{o}\text{t}\text{a}\text{l}}V=$ constant

$P_{\text{t}\text{o}\text{t}\text{a}\text{l}}=$ constant $(\frac{1}{V})$

$P_{\text{a}\text{t}\text{m}}+P_{Hg}=$constant$(\frac{1}{V})$

$P_{Hg}=$ constant $(\frac{1}{V})-P_{\text{a}\text{t}\text{m}}$

the graph is of the form $y=mx+b,$ where the slope, $m,$ gives the value of the constant, and the $P-$intercept is the negative of the atmospheric pressure.

Q$1.$ What is the slope of the line $($i$.$e$.,$ the constant in the Boyle's law equation$)?$ Give units in your answer.

Q$2.$ What is $P_{\text{a}\text{t}\text{m}}($i$.$e$.,$ the negative of the $P-$intercept$)?$ Give units in your answer.
