It depends at what temperature. If we assume that it is at its boiling point already, then you do the equation. Q=MH(f). Q= heat, m=mass, and H is the feat of fusion. For water it is 2260J/g. So do it like this. Q=1000mL * 2260J/g. You need 2260 kJ to heat 1L of water at its boiling point.
One liter of water weighs 1 kg so if it all turns to steam you will have 1 kg of steam. If the water is in an open container this will happen at 100 celsius. If it is in a closed container the pressure will rise as its temperature increases, and follow what is called the saturation line, until the Critical Point is reached at 374 celsius and 220 barg (3190psig). Beyond this temperature liquid water cannot exist and it will all have become superheated steam which will behave as a gas, with pressure being proportional to absolute temperature (kelvin)
See the nearby link for a brief but useful explanation of the ideal gas law and formula. Steam properties can be obtained from steam tables, good ones are published by spiraxsarco, also available on line.
About one pound of coal will convert 0.7 gallons of water to steam.
depends upon your water input.... if you are supplying 100 deg C water, then 540 KCal
You would produce exactly 1 kilogram of steam but it would take the place of about 6 litres depending of course on the temperature and pressure of your container

How much heat is required to produce 1kg of wet steam at 350 kilopascals from water at 20 degrees Celsius if steam is 95 percent dry?
It equals one kilpod.
Can you clean laminate flooring with steam?
No!!!! Please don't do this. You will ruin your floor. no, never. Steam cleaners and steam mops leave to much water on a laminate floor.
What is the difference between saturated steam and Superheated steam?
Saturated steam occurs when steam and water are in equilibrium. If you have a closed container of water and heat it, above 100 celsius the steam pressure will start to rise, and as the temperature continues to rise, the pressure will go on rising. What is happening is that steam is being evolved to match the temperature (steam tables will give this relation) and the steam conditions are said to be saturated because if the pressure is raised by external means, some of the steam will start to condense back to water.If the steam pressure is held at a lower level than that achieved at saturation, by taking steam off to feed a turbine or other steam usage, there is effectively an excess temperature for that pressure, and the steam is said to be superheated. It in fact then becomes dry, and behaves as a gas. The amount of superheat can be quantified as so many degrees of superheat (celsius or fahrenheit).Turbine designers want steam to be superheated before reaching the turbine, to avoid condensation causing blade erosion, and steam producing boilers in power plants are designed to produce superheated steam. In plants where no turbines are used, only satured steam is normally generated.In heating applications, saturated steam is preferable, because it has a better energy exchange capacity. Superheated steam must cool down, and become saturated steam, before condensing in a heat exchanger. Also, superheated steam is a thermal insulator, like air.That is why it is necessary to direct superheated steam through a desuperheater before using the steam in heating applications.
A steam turbine has an efficiency of 40 percent A steam engine has an efficiency of 25.0 percent Suppose both devices are provided with 1000J of thermal energy How much more useful work will the ste?
The steam turbine will produce 400 J of output, and the steam engine 250 J. That's what the efficiency figure means.
How much heating power is delivered to a load?
There is no specific ratio, as it depends on the pressure and temperature of the steam. Steam is merely water vapor, at a temperature above the boiling point of water (212 degrees F., 100 degrees C.). When water boils, and turns to steam, the steam will occupy a volume 1846 times that of the water that was converted -- at atmospheric pressure, and at the boiling point of water. Such steam is useful in cooking, for example, to steam vegetables. But in general, it is not very useful at this low pressure. Steam used in industrial processes or to drive engines or turbines, is at much higher pressures. Those pressures are obtained by vaporizing water in a closed vessel, so that the steam is allowed to occupy a volume much less than the 1846 times ratio just noted. Steam in closed vessels can build up to enormous pressures, which ultimately can rupture the vessel. Fragments ejected as shrapnel from such an explosion can have more striking power than a bullet or a cannon shell. Perhaps worse, the released steam contains enormous energy, which can for example scald a human to death almost instantly. For that reason, steam generators are provided with valves which release the steam when a desired pressure is reached. They are provided also with blowoff valves, which open at a somewhat higher pressure, in the event that the orifice or pipe through which steam is withdrawn may not be of sufficient size. Such blowoff valves vent the steam chamber into the atmosphere, or into a condensation chamber. The steam vessels are designed to withstand a pressure usually twice or more the level of pressure that triggers the blowoff valve; this is a safety measure. Because the ratio of water to steam varies, according to pressure and temperature of the steam (and whether it is "wet" steam or "dry" steam), it is more common to speak of pounds of steam. This is the weight of the water converted into steam (of the desired pressure and temperature) in a given time, such as pounds per hour. Water, as you may know, weighs 8.33 pounds per gallon. Knowing the weight of the steam is important, for example in running a steam turbine. The weight of the steam, and its velocity, determine the momentum of the steam; and that can be translated into the force or torque applied to the turbine rotor, thus the output of the turbine. That in turn translates into how many kw. of electricity the turbine-generator can produce per hour. Such computations actually get pretty complicated, but you can see that there is a relationship between the amount of water converted into steam, and the output of an engine or turbine or generator which is driven by that steam. There is a specific field of engineering (and physics) which deals with steam. It is called Thermodynamics, It is essential in designing steam boilers and steam-powered equipment.
How much does steam expand?
Water weighs 1kg per liter. If it is all turned to steam you will have 1kg of steam. Water expands to nearly 1700 times its original volume at 212 degrees.
How much water required to produce 1 ton of steam?
It would take 1 ton of water to create 1 ton of steam.
1 pound of water equals how much steam?
1 pound of water at sea level can produce approximately 26.8 cubic feet of steam.
Do the particles in steam have very low density?
Yes, the particles in steam have very low density compared to liquid water because they are widely spaced apart due to the high temperature causing them to move rapidly. This low density is why steam rises in the air.
How much tons of steam will produce if you heat 1 cubic meter water to 280 C and 64 BAR pressure?
1 M3 of water will make 1 tomme of steam
How much water is required to produce a 2 liter bottle of sweetened carbonated drinks?
132 gallons
How much steam will produce if 1 kg of water used at 170 degree temperature?
The answer will depend on the units for the temperature.
How much horse power does one liter produce?
One liter of what?

Why do you need water for distillation?
Water is needed for distillation to control the amount of alcohol and to produce steam. Much of the water is boiled off during the process but the remaining percentage dictates the proof.
How much mmbtu is required to produce one ton of steam?
The amount of MMbtu required to produce one ton of steam can vary depending on the efficiency of the boiler and the pressure of the steam. On average, it takes about 10-12 MMbtu to produce one ton of steam at standard conditions.
