Chapter 17: Problems: 5, 19, 23; 25; 66.
Additional problems:
Problem 1: A “typical” adult male consumes about 2500 kcal of food in a day. If this consumed energy is dissipated over the course of 24 hours, what is the average output power in watts?
Problem 2: A well insulated bucket contains 150 g of ice at 0o^ C. (a; 1 Point) If 20 g of steam are injected into the bucket, what is the final equilibrium temperature of the system? Is any ice left afterwards?
Problem 3: One mole of an ideal gas is heated while its volume changes, so that
T = A ⋅ P^2 , where A is a constant. The temperature changes from T 0 to^ 4*T 0. Find the work done by the gas. Express your result in terms P 0 , V 0 , the pressure and volume at temperature T 0.
