delta_t | Temperature Change(°C) | 1 |
How It Works
Specific Heat Capacity
Specific heat capacity is the energy needed to raise 1 kg of a substance by 1 degree.
Formula
c = Q / (m * DeltaT)
Rearranging Q = mcDeltaT to solve for c. This is useful in calorimetry experiments.
Worked Example
4186 J raises 1 kg of a substance by 1°C.
- 01c = Q / (m * DeltaT)
- 02c = 4186 / (1 * 1)
- 03c = 4186 J/(kg·°C)
- 04This matches water's specific heat capacity.
Frequently Asked Questions
What material has the highest specific heat?
Water at 4186 J/(kg·°C) has one of the highest specific heat capacities of any common substance, which is why it is an excellent coolant.
How is specific heat measured?
By calorimetry: add a known amount of heat to a known mass and measure the temperature change, then calculate c.
Does specific heat change with temperature?
Slightly. Most values given are averages over a temperature range. For most calculations, treating c as constant is adequate.
