Specific heat definition chemistry
WebMar 19, 2024 · A unit of heat energy used in thermochemistry is the thermochemical calorie, equal to 4.184 joules. It is commonly used as the unit for heat capacities, latent heats, and heats of reaction. WebApr 11, 2024 · Specific Heat Capacity. A substance’s specific heat capacity is the amount of energy needed to raise one kilogram of that material by one degree Celsius. 4,200 Joules per kilogram per degree Celsius (J/kg°C) is the specific heat capacity of water. So, 4,200 J are required to raise the temperature of 1 kilogram of water by 1°C.
