A phase diagram is a graphical representation of the various phases of a substance or mixture of substances that coexist in thermodynamic equilibrium, and undergo phase changes under different working conditions, such as temperature, pressure, or volume. The water system is divided into three phases: ICE (S), WATER (L), and WATER VAPOUR (G)
Phase diagrams (plots of pressure vs. temperature) were correlated with heating curves (plots of temperature vs. energy). These two types of plots provide complementary information on the phase transitions of substances.
Using the phase diagram for water, we can determine that the state of water at each temperature and pressure given are as follows: (a) solid; (b) liquid; (c) liquid; (d) gas; (e) solid; (f) gas.
In the electric water heaters and thermostat wiring and installation series, we will be showing that how to wire and install a non-continuous (non-simultaneous) dual element water heater and thermostat for 240V AC single phase (US) and 230V AC single phase (UK/EU).
In the first basic tutorial, we will be showing how to wire and install a single element water heater and thermostat for 120V AC single phase (US), 230V AC single phase (EU/UK) and 240V AC two lines US.
Example 1. Counting components. How many components are present in a system in which ammonium chloride undergoes thermal decomposition? Begin by writing down the chemical equation for the reaction and identifying the constituents of the system (all the species present) and the phases.
The hot water heater system diagram provides a visual representation of the components and flow of a typical hot water heating system. This diagram is helpful for understanding how the system functions and identifying any potential issues or areas for improvement.
