Heat capacity. The specific heat capacity of

**water**is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it**takes**4,200 J to raise the**temperature**of 1 kg of**water**by 1°C.

Accordingly, how do you calculate the energy needed to increase temperature?

**To calculate the energy required to raise the temperature of any given substance, here's what you require:**

- The mass of the material, m.
- The temperature change that occurs, ΔT.
- The specific heat capacity of the material, c (which you can look up).
- Here is a source of values of c for different substances:
- Q=m×c×ΔT.

**Energy Required for Water Heating**

- m = mass of water heated.
- Cp= the heat capacity of water (1 BTU / lb ºF)
- ΔT = temperature difference.

Subsequently, one may also ask, how many joules does it take to increase temperature?

1 Expert Answer The energy needed to raise the temperature of 15 grams of gold from 22 degrees Celsius to 85 degrees Celsius is then **121.9 Joules** or **122 Joules** (if rounded up).

Specific heat is the amount of heat required to raise one gram of any substance one degree Celsius or Kelvin. The formula for specific heat is the amount of heat absorbed or released = **mass** x specific heat x change in temperature.
