How many btus does it take to heat up one gallon of water?
That depends on what the starting temperature of the water is,and what temperature you want it to reach.If you expect to get a number, you must first give the necessary numbers.
Why does steam take up more space than liquid water?

How do you change ice to water and then water to steam?
All you need to do is keep adding heat to it. The laws of Nature and the properties of H2O take care of all the rest.
How do you explain the three states of matter to children?
Use this simple thing.... Take a glass of water and keep it your fridge.... After a few minutes, take it out and show it to them and say that they have arranged themselves very closely due to cold condition, like we like being close to others to share the warmth... Now heat it, take the beaker near your window sill (with care) and show them the vapor.... Tell them that they turned into vapor state as it was hot and have thus spread out due to the hot temperature.... That's it.... :) Take an ice cube, it is a solid state of matter. Melt this, it will be converted to water, it will be the liquid state of matter. Then boil this water, steam will appear, this steam will be the gaseous state of matter. In this way, we can explain the three state of matters, 1st is ice(solid state), 2nd is water(liquid state) and the 3rd is steam(gas) state.
What are the stages that take place in a fossil fuel power station?
The fuel gets put in a furnace in hwere it burns to produce heat, this heat is used to produce high pressure steam that is taken through pipes to a turbine, the steam is used to spin the turbine blades which generate eletrical power. the steam is then condensed back to water in cooling towers and the process starts again.
1 pound of -4 degree F ice to 284 degree F steam how many BTUs does it take?
1320 btu`s
How many btus does it take to raise of 5 pounds of water to 5 degrees Fahrenheit?
25
How many Btus will it take to raise 10 pounds of water from -5 to 220 Degrees?
2250
How many BTUs does it take to raise the temperature of water from 32 degrees to 300 degrees?
That will completely depend on how much water there is.
How many btus are required to change one pound of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit?
1)This is a 5 part question. The first is realizing that 20F to 32F uses .5BTU per pound per degree. That means it takes 32-20=12*.5=6BTUs to get the ice to 32F. 2)Then you need to know the Latent Heat of Fusion for Ice which is 144BTUs (given). Lets assumes the ice changes from ice to water instantaneously at 32F. 3)Next we calculate the BTUs from 32F to 212F. Which is 1BTU per pound per degree F. 212-32=180 so it take 180BTUS. 4)Next we have to use the Latent Heat of Vaporization of water which will say instantaneously converts water to vapor. This takes 970BTUS (given). 5)Then we calculate the BTUS from 212F to 220F. Which is .5BTUs per pound per degree F which is 220-212=8*.5=4BTUs...... Finally add up all the BTUs and you get 6+144+180+970+4=1304BTUs.
How many BTU's does it take to evaporate one pound of water?
BTUs to Evaporate One Pound of WaterQuick Answer: Somewhere around 1000BTU/lb Long answer: It depends on the temperature of the water you start with. Before you can evaporate the water, you must heat it to it's boiling point. The warmer the water you start with the fewer BTUs will be needed to heat the water to its boiling point. Keep in mind the BTUs require to raise the water to its boiling point are very few compared to the BTUs required to change the water from a liquid to a gas.One pound of steam contains 1150 BTUs. This is the energy you need to put into the water for it to evaporate if you start with water at 32F. If you start with water at 100F the water already has 70 BTU/lb so the BTUs required to evaporate the water when you start at 100F is 1150-70 = 1080 BTU and so on.You can get all this information in a steam table which can be found easily by searching the web.

How many btus does it take to raise half pound of water 1 degree?
One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.
Why does steam take up more space than liquid water?
why does steam take up more space than liquid water
Why doesnt steam take shape or size?
Because steam is a gaseous phase of water.
Why does water take up more space as steam then it does as liquid water?
Sort of, as steam water spreads around more so you could say that water takes up more space as steam.
How many BTUs does it take to heat one pound of water from 80 degree F to 212 degree F?
212 - 80 = 132 degrees temperature increase x 1 pound water = 132 BTU
