Chapter 16, Problem 12OQ

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 $\frac{1}{3}\text{L}$. (b) It decreases to $1/\sqrt{3}\text{L}$. (c) It is constant. (d) It increases to $\sqrt{3}\text{L}$. (e) It increases to 3 L. (ii) What happens to the pressure of the air in the balloon? (a) It decreases to $\frac{1}{3}\text{atm}$. (b) It decreases to $1/\sqrt{3}\text{atm}$. (c) It is constant. (d) It increases to $\sqrt{3}\text{atm}$. (e) It increases to 3 atm.
