2019/8/19 · Water and steam are great heat carriers and are not damaging to our environment. The boiling point of water at atmospheric pressure is 100 C or 212 F. By pressurizing the boiling system by giving it an airtight seal, we can actually increase the boiling point. This is how pressure cookers work.
