Does making a cup of coffee involve dissolving?

Answer 1

Yes it dissolves in water and if you want the further explaination i haveb written it down.

Coffee beans do not exactly "dissolve" in hot water. That is an oversimplification. We make coffee by a process called leaching. Which is essentially the selective dissolution of chemical compounds from a solid phase into a solvent.

When we make coffee, we dissolve a variety of chemicals responsible for flavors, colors, aromas, and stimulants (caffeine) into water. The relative amounts of the dissolved compounds dissolved depend on the contact area, the concentration gradient of chemicals between water and beans, the rate of liquid flow, the temperature of liquid, and even the pressure of the liquid and is a rather complicated process to model.

All that said, to answer your question, as temperature of the water increases, the solubility of the coffee bean chemicals in water increases which increases the driving force for transfer from bean to water.

Answer 2

no
