Answers
Explanation:
2)A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.
3)Air has molecules that are constantly moving. Because air has mass, Earth's gravity attracts it and gives it weight. Because it has weight, and the air molecules are constantly bumping into things, it exerts pressure. The Earth's atmosphere is an extremely thin layer of air.
4)The part of the stratosphere with the highest amount of ozone is commonly referred to as the “ozone layer”. Throughout the atmosphere, ozone is formed in multistep chemical processes that are initiated by sunlight.
5)Exhaled air is 4% carbon dioxide, a waste product of cellular respiration during the production of energy, which is stored as ATP. Exhalation has a complementary relationship to inhalation which together make up the respiratory cycle of a breath.
