Air is Matter: <\/strong>Air is made up of tiny particles called molecules. Even though air may seem invisible, it is a form of matter.<\/p>\n\n\n\n<p><strong>2. Molecules in Motion: These<\/strong>&nbsp;air molecules are constantly moving, colliding with each other and with objects. This motion is what we feel as wind.<\/p>\n\n\n\n<p><strong>3. Gravity&#8217;s Role:<\/strong>&nbsp;Just like any other matter, air is affected by gravity. Gravity is the force that pulls everything with mass towards the center of the Earth.<\/p>\n\n\n\n<p><strong>4. Weight Definition: <\/strong>Weight is the force with which an object is pulled toward the Earth due to gravity. So, if something has weight, it is being pulled down by gravity.<\/p>\n\n\n\n<p><strong>5. Air Has Weight: <\/strong>Since air is made up of matter and is influenced by gravity, it also has weight. The weight of the air above us pushes down on everything on the Earth&#8217;s surface.<\/p>\n\n\n\n<p><strong>6. Measuring Air Pressure:<\/strong>&nbsp;The weight of the air is what creates atmospheric pressure. Scientists use tools like barometers to measure this pressure.<\/p>\n\n\n\n<p><strong>7. Varying Air Pressure:<\/strong>&nbsp;Air pressure can change due to weather conditions. High-pressure systems are associated with fair weather, while low-pressure systems often bring storms.<\/p>\n\n\n\n<p><strong>8. Balancing Act:<\/strong>&nbsp;Air pressure is balanced and exerted evenly in all directions. This is why we don&#8217;t feel the weight of the air because it exerts equal force from all sides.<\/p>\n\n\n\n<p><strong>9. Applications:<\/strong>&nbsp;Understanding that air has weight is important in various fields, from meteorology to engineering. It helps us design structures that can withstand air pressure and study weather patterns.<\/p>\n\n\n\n<p><strong>10. Everyday Examples:<\/strong>&nbsp;Some everyday examples of air having weight include the fact that a bicycle tire needs air to support the weight of the rider, and we need to pump air into car tires to keep them properly inflated.<\/p>\n\n\n\n<p class=\"has-text-align-center has-text-color has-large-font-size\" style=\"color:#105000\"><strong>Learn with example<\/strong><\/p>\n\n\n\n<p><strong>Ballon experiment:<\/strong><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"660\" height=\"457\" src=\"https:\/\/5thclass.deltapublications.in\/wp-content\/uploads\/2024\/05\/image-4.png\" alt=\"\" class=\"wp-image-11426\" style=\"aspect-ratio:1.4442013129102844;width:316px;height:auto\" srcset=\"https:\/\/5thclass.deltapublications.in\/wp-content\/uploads\/2024\/05\/image-4.png 660w, https:\/\/5thclass.deltapublications.in\/wp-content\/uploads\/2024\/05\/image-4-300x208.png 300w\" sizes=\"auto, (max-width: 660px) 100vw, 660px\" \/><\/figure><\/div>\n\n\n<ul class=\"wp-block-list\">\n<li>Inflate the two balloons until they are equal in size and tie them off.
