We place a metal rod weighing 5.00 g with a specific heat capacity of 0.490 J/K/g in 23.5 mL of water. The specific heat capacity of water is 4.184 J/K/g and we make the approximation that its density is exactly 1.000 g/mL. The water has an initial temperature of 20.0 °C and the metal rod has an initial temperature of 81.0 °C. What is the final temperature (in oC) of the water and metal rod?
