The quality of industrial diamonds is determined in part by measuring the specific heat capacity, which is 0.5091 J/g·K for pure diamond. If the absorption of 27.64 J of heat by a 2.06 g diamond sample of unknown purity causes its temperature to rise from 25.90°C to 74.17°C, is the diamond sample pure? Explain your reasoning.
