There are no units for the temperature. The temperature change could be 230 Celsius degrees or 170 Fahrenheit degrees (94 Celsius degrees). In fact they could be in less commonly used units: eg Reaumur.

To calculate the BTUs required to cool 1 lb of water at 200 degrees Fahrenheit to ice at 30 degrees Fahrenheit, we first need to find the heat energy needed to cool the water from 200°F to 32°F (the freezing point of water) and then the additional energy needed to freeze it. The specific heat capacity of water is 1 BTU/lb°F, and the heat of fusion for water is 144 BTU/lb. So, to cool the water from 200°F to 32°F, we need (200-32) * 1 = 168 BTUs, and to freeze it, we need an additional 144 BTUs. Therefore, the total BTUs required would be 168 + 144 = 312 BTUs.

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 raise the temperature of 15 pounds of water from 100 degrees fahrenheit to 130 degrees fahrenheit?

To calculate the BTUs required to raise the temperature of 15 pounds of water, you can use the formula: BTUs = Weight of water in pounds × Temperature change in degrees Fahrenheit × 1 BTU So, the calculation would be: BTUs = 15 lbs × (130°F - 100°F) × 1 BTU = 15 lbs × 30°F = 450 BTUs.

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.


How many btus will it take to raise 50 pounds of ice at 32 degrees to water at 160 degrees?

To raise 1 pound of ice from 32°F to water at 32°F it requires 144 BTUs. Since you have 50 pounds of ice, you would need 50 * 144 BTUs to raise the ice to water at 32°F. To further raise the water from 32°F to 160°F, you would need an additional amount of BTUs based on the specific heat capacity of water.

How many btus does it take to raise 1 pound of water at 32 degrees to 212 degrees of steam?

It takes 180 BTUs to raise 1 pound of water from 32 degrees Fahrenheit to 212 degrees Fahrenheit to convert it completely into steam. This change in temperature includes heating the water from its freezing point to boiling point, then undergoing phase change from liquid to gas.


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.
