(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. 13-32 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 Weight (mass m) m atmospheric pressure outside the cooker is 1.01 X 105 Pa. Diameter d FIGURE 13-32 Problem 64. Steam Water Waterarrow_forward59. In a typical squash game (Fig. 14–21), two people hit a soft rubber ball at a wall. Assume that the ball hits the wall at a velocity of 22 m/s and bounces back at a velocity of 12 m/s, and that the kinetic energy lost in the process heats the ball. What will be the temperature increase of the ball after one bounce? (The specific heat of rubber is about 1200 J/kg•C°.) FIGURE 14-21 Problem 59.arrow_forward

The molar mass of anelement is given on the periodic table in units of grams/mole.A fire breaks out, raising the ambient temperature to 69.1◦C while 82.3 g of gas leak out of thetank.
