# If the initial volume of the bubbles in a diver's blood is 15 mL and the initial pressure is 12.75 atm, what is the volume of the bubbles when the diver has surfaced to 1.00 atm pressure?

${V}_{2} \cong 200 \cdot m L$

#### Explanation:

At constant temperature, ${P}_{1} {V}_{1} = {P}_{2} {V}_{2}$. Thus ${V}_{2}$ $=$ $\frac{{P}_{1} {V}_{1}}{P} _ 2$.

And thus, $\frac{12.75 \cdot a t m}{1 \cdot a t m} \times 15 \cdot m L$ $=$ ??

Of course, the temperature might have changed between depth and surface, but we have no way of interrogating this change. That diver is very deep $\left(> 100 \cdot m\right)$. Sports divers would never go near that depth.
