A block of copper (Cu) weighing 10 g is heated so that it receives 200 J of heat energy (q). Given the specific heat capacity of copper (0.386 J/g.°C), what will be the temperature rise of the block at the end of the heating process? Assume that no heat is lost to the surroundings. Give your answer to 1 decimal place. q = Cp . m . ΔT ΔT = q / Cp . m m = mass of the substance in grams
