What is Specific Heat Capacity?
The amount of heat energy required to raise the temperature of 1 gram of a substance by 1°C (or 1 K). Expressed in J/g·°C. Water has a high specific heat (4.18 J/g·°C), which moderates Earth's climate. Used in calorimetry: q = mcΔT.

The amount of heat energy required to raise the temperature of 1 gram of a substance by 1°C (or 1 K). Expressed in J/g·°C. Water has a high specific heat (4.18 J/g·°C), which moderates Earth's climate. Used in calorimetry: q = mcΔT.
Specific heat capacity is used in thermochemistry calculations for calorimetry experiments. Engineering uses it to design heat exchangers and thermal management systems. The high specific heat of water makes it an excellent coolant in industrial processes and biological systems.
Specific heat capacity is a physical property concept with no direct safety hazard. However, materials with low specific heat can undergo rapid temperature changes that may affect process safety.
The formula or notation for Specific Heat Capacity is: q = mcΔT; c(water) = 4.184 J g⁻¹ K⁻¹
