Homework : ) give an example where the following energy changes would take place: electric to thermal chemical to thermal electric to mechanical

1.A toaster draws electric current (electrical energy) from a wall outlet and converts these moving electric charges into heat (thermal energy) in the filaments that turn red hot to cook your toast.

2.Coal is burned at a power plant. The chemical energy released as the coal is burned heats water and turns it into steam. The chemical energy causes the liquid water molecules to move faster increasing their thermal energy.

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".
