Specific heat is measured in units of J/kg · °C (joules per kilogram-degree Centigrade), though for the sake of convenience, this is usually rendered in terms of kilojoules (kJ), or 1,000 joules—that is, kJ/kg · °C.

11 Αυγ 2024 · The unit of specific heat is Joules per gram per degree Celsius or J/g∙ ∘ C. Another unit of specific heat is calories per gram per degree Celsius or J/cal∙ ∘ C. The temperature change (∆T) in the Celsius (C) scale is the same as that in the Kelvin (K) scale, although the temperature values differ.
The units of specific heat are J/(kg ⋅ °C ⋅ °C) and J/(kg ⋅ ⋅ K). However, degrees Celsius and Kelvins are not always interchangeable. The formula for specific heat uses a difference in temperature and not absolute temperature. This is the reason that degrees Celsius may be used in place of Kelvins.
20 Μαρ 2023 · The temperature change that occurs in the fluid is measured, and the specific heat of the substance can be calculated using the formula: q = m x c x ΔT, where q is the heat absorbed or released, m is the mass of the substance, c is its specific heat, and ΔT is the temperature change. Examples of Specific Heat in Action
27 Μαΐ 2024 · The specific heat (C) can be calculated using the formula: C = q mΔT. q – the amount of heat added (in joules) m – mass of the substance (in kilograms) ΔT – change in temperature (in degrees Celsius or Kelvin)
The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00oC. The specific heat c is a property of the substance; its SI unit is J / (kg ⋅ K) or J / (kg ⋅oC). Recall that the temperature change (ΔT) is the same in units of kelvin and degrees Celsius.
The symbol c stands for the specific heat (also called “specific heat capacity”) and depends on the material and phase. The specific heat is numerically equal to the amount of heat necessary to change the temperature of \(1.00 \, kg\) of mass by \(1.00^oC\). The SI unit for specific heat is \(J/(kg \times K)\) or \(J/(kg \times ^oC)\).
