C. Vapor pressure could be lowered as in part B above, or it could be increased by, for example, increasing the temperature. To study this effect on mercury, use the data given below to make the following three graphs: a) vapor pressure of mercury as a function of Kelvin temperature b) vapor pressure of mercury as a function of reciprocal Kelvin temperature c) natural logarithm of vapor pressure of mercury as a function of reciprocal Kelvin temperature Determine the slope and the intercept for any straight lines that are obtained, and write the equation for the straight line represented by any linear graphs. d) Use your linear graph(s) to predict the vapor pressure at 400.0 K.

Transcribed Image Text:C. Vapor pressure could be lowered as in part B above, or it could be increased by, for
example, increasing the temperature. To study this effect on mercury, use the data given
below to make the following three graphs:
a) vapor pressure of mercury as a function of Kelvin temperature
b) vapor pressure of mercury as a function of reciprocal Kelvin temperature
c) natural logarithm of vapor pressure of mercury as a function of reciprocal Kelvin
temperature
Determine the slope and the intercept for any straight lines that are obtained, and write the
equation for the straight line represented by any linear graphs.
d) Use your linear graph(s) to predict the vapor pressure at 400.0 K.
