1) Explain why alveolar gas has a different composition from air. Atmospheric (external) air contains a high percentage of oxygen and nitrogen whereas alveoli gas contains a lower percentage of oxygen and a higher percentage of carbon dioxide. The differences in composition are due to the fact that gaseous exchange is taking place within the alveoli in the lungs. Oxygen is diffusing from the alveoli into the pulmonary artery and carbon dioxide is diffusing back into the alveoli from the pulmonary

Gas leak detection is the process of identifying potentially hazardous gas leaks by means of various sensors. These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected. Common sensors used today include Infrared Point Sensor‚ Ultrasonic gas detectors‚ electrochemical gas detectors‚ and Semiconductor Sensors. More recently‚ infrared imaging sensors have come into use. All of these sensors are used for a wide range of applications‚ and can be found in industrial

atomic mass of 19. Being the lightest halogen‚ it has one stable isotope‚ fluorine 19. At standard pressure and temperature‚ the element is a pale yellow gas as a liquid its a bright yellow. The electrons are located outside the nucleus of the atom. Electrons are organized in such a way that the space between them are inter dispersed. Within this space are distinct distances up to 100‚00 times away from the nucleus of the atom. Reactions with fluorine are often sudden or explosive. Many substances
