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. Web22 de set. de 2024 · The formula for specific heat capacity is given as: C = ΔQ ⁄ m ΔT Rearrange the formula in terms of Q. Q = m C ΔT = 0.5 Kg × 830 J ⁄ Kg °C× 60° C = 24900 J. Hence, the required heat to raise the sand temperature is 24900 J. Example 2: Determine the temperature difference if 40 Kg of water absorbs 400 K J of heat.
