Do you know the Six Processes of the Phase Change?

WebPhase changes occur when a substance moves from one phase/state to another. These changes are typically created by adding or removing energy. Remember, changing the energy at constant pressure is enthalpy. Changing the energy at constant volume is internal energy. These transitions are physical changes. WebPhase diagrams are combined plots of pressure-temperature equilibrium curves representing the relationships between phase transition temperatures and pressures. The point of intersection of any three curves in a phase diagram represents a substance’s triple point—the temperature and pressure at which three different phases are in ... great places to work criteria

WebTemperature is the dependent variable, and it’s placed on the y-axis. Notice that the slope of the line is positive as heat is added to ice at -10 °C. Once the ice is heated to 0 °C (the melting point of water), the line is flat (slope = 0) since no temperature change occurs as the phase change occurs.
