  A) The point where a substance can exist as a solid, liquid, or vapor at the same time at one specific pressure and temperature.
  B) The point at which the substance changes state at the same pressure, temperature, and volume.
  C) That point when the substance changes its specific gravity at the same pressure, temperature, and volume.

 Q. 3

The specific volume of a gas that occupies 30 cubic feet and weighs 3 pounds is:
 
  A) Specific Volume = 3 pounds  30 cubic feet = 900 lbs/ft3.
  B) Specific Volume = 30 cubic feet + 3 pounds = 33 lbs/ft3.
  C) Specific Volume = 3 pounds / 30 cubic feet = 0.1 lbs/ft3.
  D) Specific Volume = 30 cubic feet / 3 pounds = 10 ft3/lb.
