How much energy is taken to change water into a solid?
The same amount of energy that is required to change it from a solid to a liquid. About 334.0 kJ/kg.
If 150 grams of water changes temperature by 7.2 C how much heat energy flows?
35 kg
How much energy would you use to raise temperature of kg of water by 2 degrees Celsius?
9.6 MJ
How much water is evaporated in 1 hrAt boiling pt?
It entirely depends on how much power or rate of energy flow there is into the water, which requires the latent heat of vaporisation (2.26 x 106 Joules/kg for water) to be supplied. Thus if the energy flow is 1 kW = 1000 Joules/sec, the mass of water evaporated per second will be 1000/2.26 x 106 kg or 0.4425 x 10-3 kg, which means it will take 2260 seconds to evaporate one kg, or about 38 minutes. Obviously in a large power plant where the energy flow might be 1000 MW, this is one million times as much, and you would evaporate 1000 tonnes (a million kg) in the same time.
Is energy required for each phase change?
Yes energy reqired during each phase change process. solid to liquid(water) = 333.7 Kj/kg liquid to vapour(water) =2257.1Kj/kg
373 grams is how many kilogram?
A kilogram (kg) is 1000 grams, therefore 373 grams is .373 kg.
What is 373 grams in kilograms?
kilo = 1000kilogram = 1000g373g = 0.373kg
How do you convert 373 g into kg?
Divide by 1000. So 373 / 1000 = 0.373 kilograms.
How many kilograms are in 373 grams?
373 g = 0.373 kgTO convert from g to kg, divide by 1000.
Hydrogen fuel cells combine hydrogen and oxygen to produce water and energy Assume 1 kg of fuel is used and the mass of the water produced is 1.10 x 10-11 kg How much energy is produced by this fuel?

How many Kg are in 373g?
373 grams = 0.373 kilograms.
Which has more heat the water in a bucket or the water in a ocean?
Heat energy is count from 0 Kelvin or -273.15 C,mass of water in ocean is approximately 1.4x10^21 kg with average temperature of 283 K, mass of a bucketful of water is no more than 10 kg and the hottest it could be is no more than 373 K. Amount of heat in a bucket of water is infinitisimally neglectible compare to heat in the ocean.
If 150 grams of water changes temperature by 7.2 C how much heat energy flows?
35 kg
How much energy would you use to raise temperature of kg of water by 2 degrees Celsius?
9.6 MJ
How much energy is required to make 1 kg of steam from 1 ltr of water?
The answer will depend on the starting temperature of the water. It will also depend on the pressure.
