The table of specific heat capacities gives the volumetric heat capacity as well as the specific heat capacity of some substances and engineering materials, and (when applicable) the molar heat capacity. Generally, the most notable constant parameter is the volumetric heat capacity (at least for solids) which is around the value of 3 megajoule per cubic meter per kelvin:
WebSpecific heat represents the amount of heat required to change a unit mass of a substance by one degree Celsius. This is expressed mathematically as: q = m⋅ c ⋅ ΔT, where q - the amount of heat supplied; m - the mass of the substance; c - the respective substance's specific heat; ΔT - the change in temperature. Webinvolving heat. Experiment In the first experiment we investigated the specific heat of water. The water was heated by use of an electric current passing through a resistor. Electrical heating allowed us to determine the heat entering the system to a high accuracy. 10061ml of water was placed in a Styrofoam cup weighing 2.2grams along with a 2Ω
