A 53.71-g cube of aluminum was heated to 97.33 °C and
transferred to a beaker containing 82.15 g of SAE 20W/50 oil at
41.3 °C. Given that the specific heat capacity of the oil is 2.316
J g−1 K −1, the molar heat capacity of
aluminum is 24.55 J mol−1 K −1, and ignoring
heat losses from the assembly, what is the final temperature of the
system?
