How many btus must be removed from one pound of water at 200 for it to end up as ice at 30?

144


If one pound of water is at a temperature of 32 degrees Fahrenheit, how many BTU’s must be removed in order to create a block of ice at 17 degrees?

LATENT HEAT OF FUSION When one pound of ice melts, it absorbs 144 BTUs at a constant temperature of 32°F. If one pound of water is to be frozen into ice, 144 BTUs must be removed from the water at a constant temperature of 32°F.

313 Btu


How many btu's in office water-cooler?

There are no BTUs in an office water-cooler. But you can calculate how many BTUs are removed by the cooler. One BTU or British Thermal Unit is the amount of heat energy required to raise the temperature of one pound of water one degree Fahrenheit. There for when you remove one BTU you are lowering one pound of water one degree Fahrenheit. So if you know how many pounds of water you have and the temperature of the water you start with and the temperature of the water comming out of the cooler you can calculate how many BTUs the cooling unit of the water cooler has removed. BTU=Temp1 - Temp 2 X LB water


How many btus are required to change one pound of ice at 20 f to steam at 220 f?

It takes approximately 144 BTUs to change one pound of ice at 20°F to water at 212°F, and an additional 970 BTUs to change the water to steam at 220°F, for a total of 1114 BTUs.


How many btus does it take to turn water into steam?

It takes approximately 970 BTUs to convert one pound of water at 212°F (100°C) to steam at the same temperature.


How many btu's must be removed from one pound of water at 200f for it to end up as ice at 30f?

To convert water at 200°F to ice at 30°F, you need to remove 1 BTU to cool water from 200°F to 32°F to become ice. Then, you need to remove 144 BTUs to cool the ice from 32°F to 30°F. So, total BTUs needed to remove from one pound of water at 200°F to end up as ice at 30°F is 144 + 1 = 145 BTUs.


How many BTUS in 1 pound of steam at 212 degrees Fahrenheit?

One pound of steam at 212 degrees Fahrenheit contains 1150 BTUs of energy.


How many btus to heat water 10 degrees?

To raise the temperature of 1 pound of water by 1 degree Fahrenheit, it requires 1 BTU (British Thermal Unit). Therefore, to heat water by 10 degrees, it would require 10 BTUs per pound of water. This value may vary slightly depending on the specific heat capacity of the water.


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.


How many btus in a ton lignite coal?

There are approximately 6,700-8,300 BTUs per pound of lignite coal. A ton of lignite coal contains 20-24 million BTUs.


How many BTU will it take to change 10 pounds of ice at 20 degrees to steam at 220 degrees?

To change 10 pounds of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit, you need to supply enough energy to first melt the ice, then heat the water to the boiling point, and finally convert it to steam. This process requires approximately 180 BTUs per pound of ice to melt it, 180 BTUs per pound of water to heat it to the boiling point, and then 970 BTUs per pound of water to convert it to steam. So, for 10 pounds of ice, the total BTUs required would be around 18,300 BTUs.
