Each liter of water that is boiled will expand to 1600 liters of steam! Why any object floats or sinks:If the total volume of water displaced by any object (if that object could be pushed totally under water) has more mass than the object itself has, then that object will float with at least some part of its shape above the top level of water. At average atmospheric pressure, the expansion ratio between water in its liquid form and steam is 1:1700. CIBSE tables? If the water system is closed (say by a check valve or a blockage) the result is an increase in water system pressure as well. We like to think of this as the surrounding water and its mass "pushing" on the object on all sides, pushing it "up" into the air (or atmosphere at sea level). The change in water pressure as temperature changes is given on the vertical axis. - this answer doesn't quite agree with the one above. steam into water(really it is gas not steam) is condensation,water into steam is evaporation. c=4187 Joules per kilogram- the specific heat capacity of water.
