No, ground coffee is not instant coffee. Instant coffee is made by brewing coffee with hot water and then freeze-drying the resulting liquid. This process removes most of the moisture from the coffee, leaving behind a concentrated powder that can be reconstituted with hot water. Ground coffee, on the other hand, is simply fresh-brewed coffee that has been ground into a fine powder. While you can certainly add hot water to ground coffee to make a cup of joe, it will not dissolve in the same way as instant coffee.
