Webg × °C. This equation can be rearranged to find the amount of heat energy (q) gained or lost by a substance given its specific heat capacity (C g ), mass in grams (g) and the change in temperature (ΔT) q = m × C g × ΔT. Molar Heat Capacity of a substance is the amount of heat required to raise the temperature of 1 mole of the substance by ... Webq = CΔT and q = msΔT, so C = ms. C is the total heat capacity of the object. s is the specific heat capacity, i.e. the heat capacity per gram. If you multiply the heat capacity per gram (s) by the number of grams, you get the total …
WebSpecific heat is closely related to the concept of heat capacity. Heat capacity is the amount of heat necessary to change the temperature of a substance by 1.00 °C . In equation form, heat capacity C is C = m c, where m is mass and c is specific heat. Note that heat capacity is the same as specific heat, but without any dependence on mass.
