Emphysema, a type of Chronic Obstructive Pulmonary Disease (COPD), occurs when the walls of the alveoli (air sacs) in the lungs are damaged, becoming less elastic and, therefore, less able to exchange carbon dioxide for oxygen. Smoking Cessation: If the emphysema has been caused by smoking, the person must quit to prevent further damage. 2  Bronchodilator Drugs: These drugs, which are taken either orally or with an inhaler, help to relax and open air passages or reduce inflammation and swelling.
A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For a given pressure, different liquids boil at different temperatures. For example, water boils at 100 Â°C (212 Â°F) at sea level, but at 93.4 Â°C (200.1 Â°F) at 2,000 metres (6,600 ft) altitude.
As long as you are talking about a normal pot with or without a normal lid (i.e. not a pressure cooker) and you are reasonably close to sea level, you're right, boiling water is at 100Â°C. However, if you start to climb in altitude, that is no longer the case, at 300m, water boils at 99Â°C, at 600m, 98Â°C and so on. Wikipedia has a page with information about High altitude cooking that contains a reference table.
