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 \(J/(kg \times ^oC)\).

- 13.2: 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).
To understand how to practically determine the specific heat capacity of a substance. To be able to use the equation and understand what each term represents and the units of each term. Introduction.
14 Νοε 2018 · Specific heat is the amount of heat per unit mass needed to increase the temperature of a material by one degree Celsius or Kelvin. These three specific heat example problems will show how to find the specific heat of a material or other information involving the specific heat.
The symbol c stands for specific heat and depends on the material and phase. 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).
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.
Use the equation for heat transfer Q = m c Δ T Q = m c Δ T to express the heat transferred from the pan in terms of the mass of the pan, the specific heat of aluminum, the initial temperature of the pan, and the final temperature:
