A 900 g copper rod at 20oC has a length of 1.0000 m. The thermal expansion coefficient of copper is 17 x 10-6 oC-1, and its specific heat capacity is 0.385 kJ/kg oC. Question A: The hot copper is then quenched by dunking the entire rod in a bucket with 10 kg of water at 20oC. The specific heat capacity of water is 4.18 kJ/kg oC. If none of the water turns to steam, what is the equilibrium temperature of the copper rod and water? Answer in oC. Question B: You measure the equilibrium temperature and find that it is 24oC. If the latent heat of vaporization of water is 2,260 kJ/kg, what mass of water turned to steam? Answer in grams.
