Physics 2206 – Chapter 14: Heat 2 14.3 Heat Capacity and Specific Heat A measure of thermal inertia? Practice Question: A very hot frying pan. You accidentally let an empty iron frying pan get very hot on the stove (200 ° C or even more). What happens when you dunk it into a few inches of cool water in the bottom of the sink? Will the final temperature be midway between the initial temperatures of the water and the pan? Will the water start boiling? Assume the mass of water is roughly the same as the mass of the frying pan. Please Read: Example 14.4 (Heating water in a saucepan)

Physics 2206 – Chapter 14: Heat 3 Check Your Understanding: Iron has a specific heat that is about 3.4 times that of gold. A cube of gold and a cube of iron, both of equal mass and at 20.0 ° C, are placed in two different Styrofoam cups, each filled with 100 g of water at 40.0 ° C. The Styrofoam cups have negligible heat capacities. After equilibrium has been attained: (a) the temperature of the gold is lower than that of the iron. (b) the temperature of the gold is higher than that of the iron. (c) the temperatures of the water in the two cups are the same.
