2.1 Exercise 20

A bicycle tire contains 2.00 L of gas at an absolute pressure of $7.00 \times 10^{5} \text{N}/\text{m}^{2}$ and a temperature of $18.0 ° \text{C}$. What will its pressure be if you let out an amount of air that has a volume of $100 \text{cm}^{3}$ at atmospheric pressure? Assume tire temperature and volume remain constant.
