WebTo maintain a constant pressure, an expansion vessel is installed to contain the increase in the water volume as it expands as it heats up. The expansion vessel is divided into two compartments separated by a diaphragm. There is water on one side and air on the other side. Initially the air pressure equals the system pressure. WebThis last point describes thermal expansion —the change in size or volume of a given mass with temperature. What is the underlying cause of thermal expansion? An increase in temperature means that there’s an increase in the kinetic energy of the individual atoms.
