We learned that water has three states: ice is the solid state, water vapor is the gaseous state, and water is the liquid state. 3 How do you turn water into steam without heat? 1. In general, and unlike the effects on gases when gas pressure changes, the effect of increasing pressure on the density of water (or any liquid) is very small - liquids are not very compressible. This means that under ideal conditions, 1 part of liquid water expands to 1700 times the volume as steam when boiled. If our water is in a closed or "water-solid" system, a change in water temperature has a corresponding change in water pressure in the system. Watch out: But where there is an obstruction to that expansion, such as by a backflow preventer or check valve, pressure in the system will increase. d 3. The maximum expansion ratio (MER) refers to the biggest expansion ratio of a round section before bursting when hydrobulged at any one time without any preforming; this is an important value that can illustrate the standard of manufacturing techniques of tubular parts with changeable diameters.
