In a container with a fixed volume of 2 m3, there is saturated liquid vapor mixed water at a pressure of 100 kPa initially. In this case, three-quarters of the total mass is in the liquid phase. Then the electric heater inside the container is operated. Calculate the electrical work required to evaporate all of the liquid in the container in case of a heat loss of 120 kJ / kg from the container to the environment. Plot the process saturation curves and constant pressure curves on the T-v diagram.

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.
