The amount of energy required to raise the temperature of 1 kilogram of a substance by 1 kelvin is called?

Answer 1

Simple answer:
That number is dependent on a factor called the specific heat with units of energy per mass unit per degree of temperature change. For water and using metric units, that specific heat is about 4.2 kilowatt seconds per kilogram per degree. A watt-second is known as a Joule (J) in the SI system of units. In SI units temperature is expressed in Kelvin (K) which is like Celsius (C) but shifted by approximately positive 273. Mass is expressed in kilograms (kg) in SI units.

So if the substance is water 4200000 Joules (J) or 4.2 MJ of energy would be required.

E = 4.2 (kJ/kg/degK x 1kg x 1000 degK
E = 4200 kJ
E = 4.2 MJ.

Problems with a simple answer:
No material has an absolutely constant specific heat as it is heated and most will experience phase changes which make the calculations more difficult and specific to the material being heated. Each of the physical phases between the starting temperature (in the case of water that could be ice, liquid, steam) has to be calculated separately in a stepwise (but computationally similar) process. Finally ionization occurs in the material leading to the plasma state and this energy of electrical dissociation must also be taken into account.

Answer 2

If think that would be a Kilocalorie as a calorie is the amount of energy it takes to raise 1 gram of water 1 degree.
