A temperature-energy diagram with five sections. See long description for details.
A phase change diagram with five sections. The x-axis is thermal energy, and the y-axis is temperature in degrees Celsius. The line in section A goes up and to the right. Section B is a horizontal line at zero degrees, connecting sections A and C. Section C goes from zero to 100 degrees as a diagonal line moving upward and to the right. Section D is a horizontal line at 100 degrees, connecting sections C and E. The line of section E goes up and to the right from 100 to 200 degrees.

At Line D in the phase change diagram, water is at a horizontal line at 100 degrees Celsius. This line represents the phase change from liquid water to water vapor (gas) during boiling. Therefore, at this line, water is present in both the liquid phase (just below 100 degrees Celsius) and the gas phase (just above 100 degrees Celsius) as it undergoes the phase transition.
The correct response is:
gas and liquid
