Question:

A cylinder contains H2O (and nothing else). The outside temperature is 298 K. To analytically determine the pressure inside, you figure that the temperature of H2O must be also 298 K. Also, you shake the cylinder and realize that it is only partially filled with liquid water. You say, "Aha", consult a chart, and come up with the answer. What is the pressure (in kPa)?
