Chapter 7, Problem 114IAE

Several factors are involved in determining the cooking times required for foods in a microwave oven. One of these factors is specific heat capacity. Determine the approximate time required to warm 250 ml of chicken broth from 4°C (a typical refrigerator temperature) to 50°C in a 700 W microwave oven. Assume that the density of chicken broth is about 1 g/mL and that its specific heat capacity is approximately 4.2 J g-1 °C-1.
