A ball of iron, which may be used in the "shotput" event at a track meet, has a diameter of 12.50 cm. The density of iron is 7.874 g/cm3. If the ball is at 16.5°C and is heated by the addition of 1255 kJ of energy, what will the final temperature be? The volume of a sphere is equal to (4/3) (π) (r3), where r is the radius of the sphere and the specific heat of iron is 0.451 J/g°C. What the units.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
