Aballoon filled with air has a volume of 4.24 liters at 23.00° c. if the balloon is cooled at constant pressure to 5.00°c, what is its new volume?

, or , with p - pressure, V - volume, n - amount of substance, T - temperature in K.

Then:

,

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".
