The energy Q needed to cause a change of temperature AT to an object with mass m, is given by Q = cmAT Here c is the specific heat capacity of the object's material. Assume that 20 000 J of energy is required to rise the object's temperature by 2 degrees Celsius. Assume also that the mass of the object is 10 kg. What is the specific heat capacity of the material?

Answer:
Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC.
