What is difference between boiling and simmering​

Boiling water is water that's bubbling at 212ºF. ... Simmering, on the other hand, is slower than that nice bubbling boil. It's still very hot—195 to 211ºF—but the water in this state isn't moving as quickly and isn't producing as much steam from evaporation. Simmering water is great for soups, broths and stews.

Boiling water:

100 degrees Celsius

Simmering:

A little cooler than 100 deg. C and the water isn't moving as fast

that's what I think

clean the wound to make sure of no infections.
