Chapter 19, Problem 19.10OQ

A rubber balloon is filled with 1 L of air at 1 atm and 300 K and is then put into a cryogenic refrigerator at 100 k. The rubber remains flexible as it cools. (i) What happens to the volume of the balloon? (a) It decreases to $\frac{1}{3}$ L (b) It decreases to 1/ $\sqrt{3}$L. (c) It is constant, (d) It increases to $\sqrt{3}$ L. (e) It increases to 3L. (ii) What happens to the pressure of the air in the balloon? (a) It decreases to $\frac{1}{3}$ aim. (b) It decreases to 1 / $\sqrt{3}$ aim. (c) It is constant, (d) It increases to $\sqrt{3}$ atm. (e) It increases to 3 aim.
