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.
In a new pool, with properly balanced water, average day outside and not covered with a solar blanket, the chlorine residual from a normal shocking will, in most instances, be down to a safe level of 3.0 or less, in about 4 hours on average after the shock. When you do shock, try to always do it at dusk.
