The SI unit for specific heat is J/(kg × K) J / (k g × K) or J/(kg×o C) J / (k g × o C). (Recall that the temperature change ΔT Δ T is the same in units of kelvin and degrees Celsius.) Values of specific heat must generally be measured, because there is no simple way to calculate them precisely.

The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat.
Unlike the total heat capacity, the specific heat capacity is independent of mass or volume. It describes how much heat must be added to a unit of mass of a given substance to raise its temperature by one degree Celsius. The units of specific heat capacity are J/(kg °C) or equivalently J/(kg K).
19 Αυγ 2024 · The unit of specific heat capacity in the International System of Units (SI) is joules per kilogram per Kelvin (J/kg·K). The equation used to calculate specific heat capacity (c) is: c=Q/mΔT. Where: Q is the amount of heat added (in joules), m is the mass of the substance (in kilograms), ΔT is the change in temperature (in Celsius or Kelvin).
The SI unit for specific heat capacity is joule per kelvin per kilogram J / kg⋅K , J⋅K −1 ⋅kg −1. Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same as joule per degree Celsius per kilogram: J/(kg⋅°C).
Define heat capacity and specific heat capacity and differentiate between the two terms ; Deduce which substance will have greatest temperature changed based on specific heat capacities ; Calculate unknown variables based on known variables using the specific heat equation
2 Αυγ 2019 · Main Idea. The Specific Heat Capacity of a substance, also known as the Specific Heat, is defined as the amount of energy required to raise the temperature of one gram of the substance by one degree Celsius. Specific Heat Capacity is important, as it can determine the thermal interaction a material has with other materials.
