What is the specific heat of an unknown substance if 2000 J of energy are required to raise the temperature of 4 grams of the substance 5 degrees Celsius?
The energy required to heat a substance is related by the formula: Q = mCpΔT ; where Q is the energy, m is the mass of the substance, Cp is the specific heat capacity and ΔT is the change in temperature. 2000 = (4)(Cp)(5) Cp = 100 Joules / g °C
