An empty glass tumbler lowered into a glass beaker containing water, when tilted shows bubbles of air coming out but when not tilted no bobbles are seen. Give reason
Dear student,
This is because, when we tilt the glass tumbler, the water enters inside it, which leads to the pushing of the air out of the glass tumbler.So, air comes out in the form of bubbles in water present in the glass beaker. This is because when the tumbler is not tilted, the water pressure is same all around the mouth of the tumbler.But, when tilted, the water pressure is higher on the lower side of the tumbler. This high pressure pushes the air from one end and the bubbles are seen in the water.
Hence, an empty glass tumbler lowered into a glass beaker containing water, when tilted shows bubbles of air coming out but when not tilted no bobbles are seen.
Regards
