How much heat must be removed from 10 pounds of 32 degree water to turn it into 10 pounds of ice at 32 degrees?
We must first know the heat of fusion of water, which is the required energy to melt a given quantity of ice. For water, this is 334 J/g. 334 Joules have to be applied to one gram of 32°F ice to melt it, so 334 Joules have to be taken out of one gram of 32°F water to freeze it.
10 pounds is 4,535.9237 grams, so (4,535.9237) * 334 gives us 1,514,998.52, the amount of energy in Joules that has to be removed from 10 pounds of water to freeze it.
The final answer is 1.51499852 MJ (megajoules)

How many Btu are required to change 600 pounds of water at 75 degrees F to steam at 212 degrees F?
1 BTU is required to raise 1lb of water 1 degree F in 1 hour. 212-75=137 degrees 600 lbs water x 137 degrees= 82,200 BTU's required to change 75 degree water to 212 degree water. To change 212 degree water to 212 degree steam it requires 970 btu's (latent heat of vaporization) per lb of water 970 btu x 600 lbs water = 582,000 btu Answer - 582,000 btu+ 82,200 btu = 664,200 btu's
The amount of heat removed to lower the temperature of 15 pounds of water from 48 degrees f to 39 degrees f is?
135 btu
How many btu does it take to raise the temperature of 1 gallon of water 1 degree if water was already 50 degrees?
U.S.gallon = 8.33 pounds of water. Therefore to raise the temperature by one degree F will require 8.33 BTU. The initial temperature of 50 F is inconsequential.
What is larger a Celsius degree or a Fahrenheit degree?
1 Degree of Celsius is larger. The number of degrees Fahrenheit between Water freezing (32) and boiling(212) is 180 degrees. The number of degrees Celsius is 100 degrees. So the Celsius degree has more value.
Freezing point of water in degrees Celsius?
0 degree
How many Btu's need to be removed from lb of water to change degrees to degrees?
To change the temperature of water by one degree Fahrenheit, 1 Btu of heat must be added or removed from 1 pound of water.
