Of water, 32 degrees.
The latent heat of vaporization of water at 212 degrees Fahrenheit at atmospheric pressure involving only vaporization and no saturation is 970 BTU/lb, so to evaporate 15 lbs of water we need 970 x 15 = 14550 BTU's
212-65=147. 147(20)=2940 btu needed is this right?
32 is the Temperature in Degrees Fahrenheit at which Water Freezes
300
200 BTU. I'm assuming your temperatures are in Fahrenheit, since all of your other measurements are in the Imperial system. A BTU is defined as the amount of energy required to raise the temperature of 1 pound water by 1 degree F, so the temperature is raised by 20 degrees, and 10 pounds of water: 20 x 10 = 200
About 8.35 pounds.
Water boils at 212 degrees Fahrenheit
Water freezes at 32 degrees Fahrenheit.
32 degrees Fahrenheit at which water freezes
32 is the temperature in degrees Fahrenheit there is also an expanded version of this which reads 32 is the T in D F at which W F 32 is the temperature in degrees Fahrenheit at which water freezes
what is the answer to this
2250
Water freezes at 32 degrees Fahrenheit and boils at 212 degrees Fahrenheit.
Water boils at 212 degrees Fahrenheit
Water boils at 212 degrees Fahrenheit at sea level.
None. Changing water from 25 degrees C to 5 degrees C requires heat to be REMOVED, not added!
