Randall D. Knight — Work, Heat, and the First Law of Thermodynamics: Problem 76

\((1200 \times 10^{-6} \text{ m}^3)(13,600 \text{ kg/m}^3) \times (140 \text{ J/kg K})(90^\circ\text{C} - 15^\circ\text{C}) + (0.50 \text{ kg})(449 \text{ J/kg K})(90^\circ\text{C} - T_i) = 0\) In Problems 75 through 77 you are given the equation used to solve a problem. For each of these, you are to: a. Write a realistic problem for which this is the correct equation. b. Finish the solution of the problem.
