Q. Which of the following set of variables give a straight line with a negative slope when plotted? $(p = apour\ pressure,\ T = temperature\ in\ K)$ $y -$axis $x -$axis
A) $p\ \ \ \ \ \ \ \ \ \ \ T$
B) $\log_{10}p\ \ T$
C) $\log_{10}p\ \ \frac{1}{T}$
D) $\log_{10}p\ \ \log_{10}\frac{1}{T}$
Explanation
(c)
$\frac{1}{T}\ on\ x$ axis and $\log_{10}p\ on\ y$ axis gives a straight line with a negative slope.
