Specific Heat of Common Materials
The specific heat capacity of various substances at room temperature. Higher values mean the material requires more energy to change its temperature.

Specific Heat Capacity FAQ
Everything you need to understand thermodynamics, from the basic Q = mcΔT formula to real-world material properties.
Specific heat capacity is the amount of heat energy required to raise the temperature of one unit of mass of a substance by one degree. It is a measure of how well a material stores thermal energy. Substances with high specific heat, like water, require a lot of energy to change temperature, while metals have low specific heat and change temperature quickly.
The fundamental formula is Q = mcΔT, where Q is the heat energy added or removed, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature. You can rearrange this formula to solve for any variable: c = Q / (mΔT), m = Q / (cΔT), or ΔT = Q / (mc).
The SI unit for specific heat capacity is Joules per kilogram per degree Celsius (J/(kg·°C)) or Joules per kilogram per Kelvin (J/(kg·K)). In chemistry, it is often expressed in Joules per gram per degree Celsius (J/(g·°C)) or calories per gram per degree Celsius (cal/(g·°C)).
Water has an unusually high specific heat capacity (4,184 J/(kg·°C)) due to hydrogen bonding between its molecules. These bonds require a significant amount of energy to break, meaning water can absorb a lot of heat before its temperature rises. This property helps regulate Earth’s climate and makes water an excellent coolant.
Specific heat capacity measures how much energy a material can store, while thermal conductivity measures how quickly heat passes through it. For example, water has a very high specific heat (stores a lot of energy) but relatively low thermal conductivity (transfers heat slowly). Metals like copper have low specific heat but very high thermal conductivity.
