Air is a Mixture:<\/strong>&nbsp;Air is a mixture of gases that surround the Earth. It&#8217;s a combination of different substances.<\/p>\n\n\n\n<p><strong>2. Major Components:<\/strong>&nbsp;The two major components of air are nitrogen and oxygen. Nitrogen makes up about 78% of the air, while oxygen makes up about 21%.<\/p>\n\n\n\n<p><strong>3. Other Gases:<\/strong>&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In addition to nitrogen and oxygen, air also contains small amounts of other gases, such as carbon dioxide (about 0.04%), argon, and trace amounts of other gases like neon and helium.<\/li>\n\n\n\n<li>Other gases such as Neon, Hydrogen, water vapor, etc. are also present in small quantities.<\/li>\n<\/ul>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group has-large-font-size\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<p><strong>4. Importance of Oxygen:<\/strong>&nbsp;Oxygen is essential for living organisms. We breathe in oxygen from the air, and it is used by our bodies to produce energy.<\/p>\n\n\n\n<p><strong>5. Role of Nitrogen:<\/strong>&nbsp;Nitrogen is not used by most living things directly, but it plays a vital role in the Earth&#8217;s atmosphere, maintaining atmospheric pressure and diluting oxygen to safe levels for breathing.<\/p>\n\n\n\n<p><strong>6. Carbon Dioxide:<\/strong>&nbsp;Carbon dioxide is a greenhouse gas present in small amounts in the air. It&#8217;s important for photosynthesis in plants, but too much of it in the atmosphere can contribute to global warming.<\/p>\n\n\n\n<p><strong>7. Water Vapor:<\/strong>&nbsp;Air also contains water vapor, especially in humid conditions. Water vapor plays a significant role in weather and can form clouds and precipitation.<\/p>\n\n\n\n<p><strong>8. Pollutants:<\/strong>&nbsp;In addition to natural gases, air can also contain pollutants from human activities, such as smog, which is a combination of smoke and fog. These pollutants can be harmful to both the environment and human health.<\/p>\n\n\n\n<p><strong>9. Clean Air:<\/strong>&nbsp;Clean air is essential for our health and the environment. It&#8217;s important to reduce air pollution and take steps to improve air quality.<\/p>\n\n\n\n<p><strong>10. Air Composition Varies:<\/strong>&nbsp;The composition of air can vary slightly depending on location and conditions. For example, at high altitudes, the proportion of oxygen is lower.<\/p>\n\n\n\n<p class=\"has-text-color\" style=\"color:#d90000\"><strong>Let&#8217;s practice!<\/strong><\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/wordwall.net\/play\/81974\/879\/849\"><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"500\" src=\"https:\/\/5thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-3-79.png\" alt=\"\" class=\"wp-image-5290\" srcset=\"https:\/\/5thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-3-79.png 500w, https:\/\/5thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-3-79-300x300.png 300w, https:\/\/5thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-3-79-150x150.png 150w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/wordwall.net\/play\/82736\/280\/788\"><img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"500\" src=\"https:\/\/5thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-1-2-81.png\" alt=\"\" class=\"wp-image-5291\" srcset=\"https:\/\/5thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-1-2-81.png 500w, https:\/\/5thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-1-2-81-300x300.png 300w, https:\/\/5thclass.deltapublications.in\/wp-content\/uploads\/2023\/03\/Worksheet-1-1-2-81-150x150.png 150w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/figure>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>What Does Air Contain? what does the air contains by Delta publications Key Notes 1.
