WebTo calculate the specific heat of the selected substance, we can use the following formula: c = \dfrac {\Delta Q} {m \times \Delta T} c = m×ΔT ΔQ where: c c - specific heat of the substance, \Delta Q ΔQ - amount of heat delivered, m m - mass of the heated sample, \Delta T ΔT - noted temperature change. Web14 mrt. 2024 · Given, Q = 600 Kcal. M = 20 Kg. Formula for latent heat is given as: L = Q ⁄ M. = 600 / 20. = 30 Kcal/Kg. Hence, the latent heat required for phase change is 30 Kcal / Kg. Example 2: Find the mass of ice required to lower the temperature of 500 g of water at 20°C to water at 0°C.
