Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substance as long as the chemical composition is the same for all phases. These substances mainly have a constant/ uniform composition. The substances also have fixed boiling and melting points. A pure substance takes part in a chemical reaction to form predictable products.

Q2. Consider a piston-cylinder device that contains liquid water at 1 MPa and 150 °C. The weights on top of the piston are removed one by one so that the pressure inside the cylinder decreases gradually (Fig. 3–18). Draw a property diagram that shows all the water states including phase change processes, which will go from compressed liquid to super-heated vapor while keeping the temperature constant in the system. P = 1 MPa T = 150°C Heat

At the pressure of P=0.1MPa, the saturation temperature of water is Tsat=100 ºC, the specific volume of the saturated liquid water is vf=0.001043 m3/kg, and the specific volume of the saturated vapor water is vg=1.6720 m3/kg. (3) Please match regions shown in the diagram with correct names.
1.00×104 cm³ of 200 °C steam at a pressure of 10.0 atm is cooled until the volume of the liquid water? condenses. What is Part A Give your answer in cm³. Express your answer with the appropriate units.
A container holds 75.2 liters of Oxygen at 271.4K and a pressure of 3.87 atmospheres. How much heat is required to raise the temperature of this gas to 296.4K, holding the volume constant? Give your answer in kJ. Treat the gas as an ideal gas. Note: It is understood that your answer is in units of kilo-Joules, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit ("kJ" in this case), you answer will be counted wrong.
