If a piece of iron with a temperature of 300 degrees celsius is dropped into a gallon of water with a temperature of 25 degrees Celsius heat will?
heat will flow from the iron to the water until both are the same temperature
How many therms does it take to heat 30 gallons of hot water?
That's going to depend on the temperature of the water before you heat it, and on how hot you want it to be when you're done.
How many BTUs will it take to change 1 gallon of water at 32 degrees to ice at 32 degrees?
You would need to remove approximately 1200 BTUs of heat to convert a gallon of water to ice. There are 8.34 lb in a gallon of water, which converting to lb-moles is 0.463. The latent heat of crystallization for water is -2583.4 BTU/lb-mole. Multiplying the two together and you get -1197 BTUs, which means you need to remove that amount of heat to convert the gallon of water to ice.
How many watts is required to heat 1 gallon of water from 50 degrees F to 180 degrees F?
"Watt" is a rate of moving energy. The more watts you use, the faster the waterwill heat up. The fewer watts you use, the slower it will heat. If you can affordthe time to wait, then any amount of power will do the job, no matter how small.
How many btu's of heat energy are needed to raise the temperature of 12 gallons of water from 50 degrees Fahrenheit to 130 degrees Fahrenheit?
answer: 7680 btu 1 gallon= 8 lb 130F-50F=80F 12G*8LB*80F=7680 BTU
What is the heat of 1 gallon of water at 170 degrees?
170o
How many Kilowatts are use used by the average tank water heater to heat 1 gallon of water from 18 degrees Celsius to 45 degrees?
no

How many gallons of hot water does it take to heat 1 gallon of cold to 72 degrees?
That depends on the starting temperature of the cold water and the starting temperature of the hot water.
How long does a 40 gallon electric heat water heater at 140 degrees take to heat up after restarting with cold water?
depends on the wattage of the elements along with the temp of the cold water but i would guess an hour or two
Is heat measured in degrees?
No. Heat is one of many forms of energy, and is measured in units of energy ... joules, calories, watt-seconds, BTU, foot-pounds, etc. "Degrees" describe the temperature of an object or a sample of a substance. That's a measure of how "full of heat" it is. One joule of heat will fill an ounce of water higher than the same joule will fill a gallon of water. So after absorbing the same amount of heat, the temperature of the ounce is higher than the gallon's temperature.
Is the heat intensity of water at 100 degrees celsius the same as the heat intensity of water 212 degrees Fahrenheit?
100 degrees celsius are equal to 212 degrees fahrenheit.
How many BTUs does it take to heat 390 gallon tank of water from 60 degrees to 248 degrees?
The specific heat of water is 1 BTU per pound per degree Fahrenheit. There are 8.3378 lbs/gallon at 60 degrees, which equals 3251.742 pounds of water. The number of BTUs to raise it 188 degrees is then 611,327.496 BTUs.
How much heat comes off an 8 X 20 foot 3000 gallon indoor pool kept at 82 degrees?
not much since the water doesn't usually release very much heat
What is Thermal convection?
The transfer of heat (therms) through fluid (including air) motion.
