Textbook Question
Chapter 18, Problem 35P
(II) A pressure cooker is a sealed pot designed to cook food with the steam produced by boiling water somewhat above 100°C. The pressure cooker in Fig. 18–17 uses a weight of mass m to allow steam to escape at a certain pressure through a small hole (diameter d) in the cooker’s lid. If d = 3.0 mm, what should m be in order to cook food at 120°C? Assume that atmospheric pressure outside the cooker is 1.01 × 105 Pa.
