Measure specific heat capacity
WebJan 7, 2024 · The specific heat capacity ( c) of a substance, commonly called its specific heat, is the quantity of heat required to raise the temperature of 1 gram of a substance by … WebPart 1: Heat Capacity of a Calorimeter. The amount of heat needed to increase the temperature of a specified quantity of a substance by one degree is known as the heat capacity, or C, of the substance. The relationship between heat capacity and specific heat is C = m×sp_heat. Therefore, q = C×Δt and C = q ÷ Δt.
