Definition
Meaning and Definition
The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius (or Kelvin).
In physics and chemistry, a property that characterizes how much energy a substance stores as thermal energy for a given temperature change. Can also refer to the heat capacity per unit mass.

- Misspelling as 'specifik heat'.
- Confusing 'specific heat' with 'latent heat'.
FAQ
Frequently Asked Questions
No. Heat capacity is the total heat needed to raise an object's temperature. Specific heat is heat capacity per unit mass (e.g., per gram or per kilogram).
Joules per gram per degree Celsius (J/g°C) or Joules per kilogram per Kelvin (J/kg·K). Both are equivalent as a change of 1°C equals a change of 1K.
Water's high specific heat means oceans and large lakes absorb and release large amounts of heat with little temperature change, moderating Earth's climate and creating milder coastal weather.
Yes, for most substances, specific heat is not constant and varies with temperature and pressure, especially over large temperature ranges. Tables often give average values.
The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius (or Kelvin).
Specific heat is usually technical/scientific in register.
Specific heat: in British English it is pronounced /spəˌsɪfɪk ˈhiːt/, and in American English it is pronounced /spəˌsɪfɪk ˈhit/. Tap the audio buttons above to hear it.

Mnemonic
Think: SPECIFIC to a substance, HEAT needed to warm it. 'Water's high specific heat is why pools stay cool longer.'
Conceptual Metaphor
Thermal Inertia: A substance's specific heat is like its 'thermal stubbornness'—high specific heat means it 'resists' changing temperature.
