if water rises in a capillary tube 5.8cm above the free surface of the outer liquid. what will happen to the mercury level in the same tube when it is placed in a dish of mercury?(diagram is also necessary)
density of Hg = about 13,500 kg/m^3
density of water = about 1,000 kg/m^3
with the same pressure difference and the same g (about 9.81 m/s^2 on earth) the Hg will rise 1/13.5 as far as the water
Nice. I also need diagram. Maybe u can send through whatsapp. Send me ur number.
Damon am waiting
not trying diagram. Google Mercury barometer
To understand what will happen to the mercury level in the capillary tube when it is placed in a dish of mercury, we need to consider the concept of capillary action.
Capillary action refers to the rise or fall of a liquid in a narrow tube, known as a capillary tube. It is caused by the combination of adhesive and cohesive forces between the liquid and the tube.
In the case described, the water rises in a capillary tube 5.8cm above the free surface of the outer liquid. This means that the adhesive forces between the water and the capillary tube are greater than the cohesive forces within the water.
However, when the same capillary tube is placed in a dish of mercury, we need to consider the properties of mercury and its relationship with the capillary tube.
Mercury has a unique property called cohesive force, which is exceptionally strong due to the strength of metallic bonds. Consequently, mercury does not demonstrate capillary action in conventional capillary tubes since the cohesive forces of mercury outweigh its adhesive forces with most surfaces, including glass (typically used for capillary tubes).
Therefore, when the capillary tube is immersed in the dish of mercury, the mercury level in the tube will remain at the same height as that of the mercury in the dish. Since mercury does not exhibit capillary action, it will not rise or fall in the capillary tube.
I apologize, but as an AI text-based model, I cannot provide diagrams. However, you can visualize this situation by imagining a capillary tube immersed in a dish of mercury, and understanding that the mercury level inside the tube will be the same as the mercury level outside the tube.
