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.
Water usually boils at 212F or 100C at sea level. As you go higher up in the atmosphere (higher altitude), the amount of atmosphere pushing down on you decreases, hence the pressure decreases. Water boils when the vapor pressure of the water equals the atmospheric pressure.Vapor pressure increases with increasing temperature, so when there is less atmospheric pressure, a smaller vapor pressure is required to get the water boiling, hence a lower boiling temperature.bharathy Â· 2 years ago.ater boils when the vapor pressure of the water equals the atmospheric pressure.
