There isn't a "formula" for this. Or, at least, you haven't been specific enough for us to tell you what the governing formula is.
Chemists usually indicate that heat is necessary for a chemical equation by putting a delta-H either over or under the reaction arrow (the meaning is the same either way).
In cold weather the water boiler which provides central heating and water heating uses the most energy.
All liquids expand on heating (apart from water between 0oC to 4oC)
Cooling or Heating First of all we have 3 phases, Gas, Liquid and Solid to change from gas to liquid to solid, cooling is required and to change from solid to liquid to gas, heating is required This type of heat is called latent heat, always think of water as an example Ice --> Water , heating Water--> Water Vapour, more heating
Yes, there is a 'water fill level' inside that you can't miss. Yes you can use it without water, but, only with the massage mode. DO NOT use heating mode without water. It will fry the heating elements.
change in state.
Molecular formula of water is H2O .It is in liquid form it can converted into gaseous form by heating it to 100 degree Celsius
describe how heating can change the water
The formula for heating ammonia is: NH4OH yields NH3 + H2O
Hot water baseboard heating is called a Hydronic heating system.
Sun heating water, normally for domestic use,
Assuming by heating gas you mean "natural" gas, the the formula would be CH4 which is methane. Natural gas is mostly methane with some other combustible hydrocarbons added in.
Underfloor heating is used to help with controlling the temperature in the house with the convection heating method. If water get on the floor, the water will condensate into steam.
can a home hot water heating system (radiators) be converted to gas fueled from oil fueled heating meathods?
The magnesium nitride has the chemical formula Mg3N2.
Oxygen
Water is heavier.
An integrated system for both space and water heating. Heating is accomplished in a condensing heating module having a small hot water storage reservoir to reduce burner cycling during periods of low demand. The space heating system includes a fluid flow loop with a fluid circulating pump for circulating a heat transfer fluid in the loop from the heating module to a remote space heating heat exchanger. The heating module can also supply hot water for service use. The system may be configured either as an open loop system, in which the space heating and water heating subsystem are combined and share common lines, or a closed loop system, in which the space heating subsystem fluid flow loop is isolated from the water heating subsystem.
