Which of the following statements is false?
A. Liquid water, at 373.15 K and 101.325 kPa, is a saturated liquid.
B. If a compound is initially a saturated liquid, and small amount of heat is removed while the pressure is held constant, then a small amount of the liquid will be converted into vapor.
C. Water vapor, at 378.15 K and 101.325 kPa, is a superheated vapor.
D. If a compound is initially a superheated vapor, and it is compressed isothermally, the pressure at which condensation begins is called the vapor pressure.
E. Water cannot be isochorically boiled.
A. Incorrect. This statement is true. The water is saturated, and adding further heat, or lowering pressure, will cause it to vaporize.
B. Correct. This statement is reversed. If a small amount of heat is ADDED to the saturated liquid at constant pressure, then a small amount of liquid is vaporized.
C. Incorrect. This statement is true. When removing heat from a vapor causes its temperature to drop, rather than to condense, it is superheated.
D. Incorrect. This statement is true. Review the phase diagram in Figure 2-1 and definitions of terms.
E. Incorrect. This statement is true. A liquid-vapor phase change typically entails a significant change in density.
