Which of the following statements is true?
A. Liquid water, at 348.15 K and 101.325 kPa, is a saturated liquid.
B. If a compound is initially a saturated liquid, and heat is added while the pressure is held constant, then the temperature of the liquid will increase.
C. If a compound is initially a saturated liquid, and its temperature is increased but it remains a liquid, then the pressure must have also increased.
D. If a compound is initially a saturated liquid, and it is compressed isothermally, it will start to boil.
E. None of the above are true.
A. Incorrect. At atmospheric pressure (101.325 kPa), water is saturated (will boil) at 373.15 K.
B. Incorrect. If heat is added to a saturated liquid at constant pressure, the liquid will undergo a phase change to vapor. The temperature of the liquid will NOT change unless heat is removed.
C. Correct. Heating a saturated liquid will boil it unless the pressure concurrently increases, increasing the boiling temperature.
D. Incorrect. Higher pressure favors the liquid phase compared to vapor. Increasing the pressure at constant temperature will make it a compressed liquid, not boil it.
E. Incorrect. One of the statements is true.
