Specific heat capacity vs heat capacity
WebIn thermodynamics, the specific heat capacity (symbol c) of a substance is the heat capacity of a sample of the substance divided by the mass of the sample, also sometimes referred to as massic heat capacity. Informally, it is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in ... WebNov 2, 2024 · 3. If we heat an amount m of a substance with specific heat capacity c p, from an initial temperaure T 1 to a final temperature T 2, then the amount of heat energy Q needed (in the absence of any losses of course) is: Q = ∫ T 1 T 2 m c p ( T) d T. Assuming m to be constant and c p ( T) invariant to T the formula reduces to: Q = m c p ( T 2 ...
