Why do small solid crystals dissolve in liquid more quickly than large crystals?
What radius needle should be used to inject a volume of 546 cm3 of a solution into a patient in 31 min? Assume the length of the needle is 2.5 cm and that the solution is elevated 1.0 m above the point of injection. Further, assume the viscosity and density of the solution are those of pure water, and that the pressure inside the vein is atmospheric.

A typical chromium doping level of a ruby rod is $0.050 \%$ by mass. How many chromium atoms are there in a ruby rod of diameter $1.15 \mathrm{~cm}$ and length $15.2 \mathrm{~cm}$ ? The density of corundum $\left(\mathrm{Al}_{2} \mathrm{O}_{3}\right)$ is $4.05 \mathrm{~g} \cdot \mathrm{cm}^{-3}$, and you can assume that the doping with chromium has no effect on the density of the solid. Now suppose all the chromium atoms are in the upper lasing level. If a laser pulse of $100 \mathrm{ps}$ is generated by the simultaneous stimulated emission of all the chromium atoms, determine the radiant power of the laser pulse. (See Table 15.2.)
