Solution: Using the graph, determine the following.The temperature at which the vapor pressure equals 300 torr.

Problem

Using the graphThe x-axis is temperature (degrees C) ranging from negative 30 to 50 with intervals of 20. The y-axis is vapor pressure (torr) ranging from 0 to 800 with intervals of 100. The data are described in the table below; values are approximate.  At -30 degrees Celsius, vapor pressure is 30 torrs.  At -10 Celsius, 90 torr, 10 Celsius is 200 torr, 30 Celsius is 400 torr and 45 Celsius is 800 torr., determine the following.

The temperature at which the vapor pressure equals 300 torr.
