The process is called sublimation. Solids can turn directly into gases, and gases can turn directly into solid without ever being a liquid. Carbon dioxide (dry ice) is a commo â¦ n example of this. Other examples are mothballs, solid air fresheners (Air Wick), and iodine.
When you start itching from chlorine, get out of the pool and limit your exposure to the chemical. Chlorine-related rash and itching typically subsides within two to four weeks. Hydrocortisone creams help relieve the itchiness.
Re: How long should a 3 chlorine puck last? When I use my feeder, I load it to the top, I think that is 9 pucks. I usually have it on about 2.0 and they can last the whole week.
