A 27.5g piece of aluminum sits in a room and cools. It loses 6120.0 J of heat. If the initial temperature of aluminum is 157.3°C, what is the final temperature? The specific heat
capacity of aluminum is 0.900 J/gºC.

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".
