WebSolar balloons are balloons in which the inside air gets heat and expands in the envelope (Use of fabric to contain the air). Then the air ( contained in an envelope) becomes lighter than the surrounding air. It causes the Balloons to float in the sky. As the name suggests, a hot air balloon works on the principle of lift (buoyancy) caused due ... Webis balanced by the drag of the balloon raising through the air. Since this depends upon the air density, it will change with altitude. Here we calculate it at the surface of the Earth. As the balloon raises, the pressure outside the balloon falls. Since the balloon is essentially in equilibrium, the pressure inside the balloon will also
