Making a new example for domestic water heating, entering water temperature in North America is around 10 C or 50 F (or colder, below 40F in northern areas such as northern Minnesota). In other words, if we start at a given or known water pressure (such as incoming building water pressure) and we then heat water in the water tank, how much will water tank pressure increase for a given rise in temperature? Calculate the pressure or force: mass / area = pressure per unit of area. At a normal atmospheric pressure of 14.7 pounds per square inch, water boils at 212 degrees Fahrenheit and expands in volume by a factor of 1700 to 1. Heat is then added and the fluid expands at constant pressure until it reaches a saturated vapor state. When water boils and turns from a liquid into a gas, the gaseous form fills a much larger area. One way to translate these into a single number is to look at the change in water density. At average atmospheric pressure, the expansion ratio between water in its liquid form and steam is 1:1700. The cookie is used to store the user consent for the cookies in the category "Performance". It does not store any personal data. Steam is not hotter than boiling water, its the same temperature.

But since the water pressure vs. water temperature lines are not straight (they're curved) while you can read the approximate density (or pressure) change as a function of water temperature right off the chart shown here, to know the precise change in water pressure if it is heated from one temperature to another requires some calculation. Even with this much pressure, water only compresses less than one percent. for every degree C that we increase the temperature of one unit (any unit-volume measurement) of water. But two different events affect the pressure and density of water in the tank: So you can see that there are two forces, both temperature and pressure, at work at once. To a reasonable approximation steam at 100C can be treated as an ideal gas. So 1000 lbs of steam (H2O in vapor phase) will condense to 1000 lbs of water (H2O in liquid phase).
