Problem

Calculate the heat, in joules, required to warm 100 g100\,\text{g} of ethanol from 10 ∘C10\,^{\circ}\text{C} to 55 ∘C55\,^{\circ}\text{C}. (The specific heat capacity of ethanol is 2.44 J g−1 ∘C−12.44\,\text{J}\,\text{g}^{-1}\,^{\circ}\text{C}^{-1} and remains constant over this range.) (a) 1.34×104 J1.34\times 10^{4}\,\text{J} (b) 7.93×103 J7.93\times 10^{3}\,\text{J} (c) 1.10×104 J1.10\times 10^{4}\,\text{J} (d) 1.88×104 J1.88\times 10^{4}\,\text{J}
