One pound mass of water in a piston-cylinder assembly, initially a saturated liquid at 45 lb/in², undergoes a constant pressure, internally reversible expansion to x₂ = 90%. For this reversible process, determine the work by integrating p dV and the heat transfer by integrating T ds, each in Btu. Step 1 * Your answer is incorrect. Determine the work by integrating p dV for this reversible process, in Btu. W12= i 835.77 Btu

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.
