Why is water rise in capillary tube wheras mercury falls in capillary tube?
This happens due to the difference in adhesive and cohesive forces. Water molecules are more attracted to the walls of the tube (adhesive forces) than to each other (cohesive forces), causing water to rise. Mercury has stronger cohesive forces compared to adhesive forces, so mercury is more attracted to itself than to the walls of the tube, causing it to be depressed or fall in the capillary tube.
Why does the liquid in the reservoir go up the tube?
The liquid rises up the tube due to capillary action, which is the ability of a liquid to flow in narrow spaces without the assistance of external forces like gravity. This occurs because the adhesive forces between the liquid and the tube are stronger than the cohesive forces within the liquid itself.
Water is able to move up the sides of a narrow tube by a process called?
capillary action. This process occurs because the adhesive forces between the water molecules and the tube's material are stronger than the cohesive forces between the water molecules themselves, allowing the water to defy gravity and rise up the tube.
When does the meniscus of a liquid in a glass tube curve downward?
A meniscus is caused by surface tension and It curves down (concave) when the liquid adheres to the container more than to itself, like water and glass. Mercury clings more to itself than glass, so it is curved up (convex)
Why the surface of the mercury in a glass tube is con vex end that of water concave?
Mercury has a low adhesive force to glass, it would rather bond to itself than another surface. This tends to create a spherical surface on open mercuric faces. Balanced by gravity the hemisphere flattens and creates the slight convex shape observed.
What has more volume square tube or round tube?
The answer depends on the cross-sectional area as well as the length.
What is stronger a 4 inch X 2 inch steel tube or 4 inch steel channel over a 5 foot span?
I assume you mean a 4 x 2 square tube that is loaded in the direction of the 4 inch dimension; then it is stronger than a 4 inch channel with flange width of 2 inches loaded in the direction of the 4 inch dimension, because the square tube has more inertia
Is a tube stronger than a solid bar?
In general, a tube is stronger than a solid bar when subject to torsional loads, because the material is distributed away from the center axis. However, a solid bar is usually stronger than a tube when subjected to bending loads, because it does not have hollow sections where stress concentration can occur. The specific strength comparison between a tube and a solid bar depends on their dimensions, material properties, and the type of load applied.
What is the area of a round tube that is 6 diamiter by 18 tall?
The total surface area is 395.8 square units.
How does a mortar fire its ammunition?
Most mortars are muzzleloaders. The mortar tube is a piece of pipe with a firing pin permanently fixed at the base. When the mortar round is dropped into the tube, the primer in the base of the round strikes the firing pin, and the round shoots out the other end. The Russians have fielded breechloading mortars. These are nothing but huge. The LITTLE one fires a 160mm round through a three-meter tube--the tube is in two sections, and the round is placed in the lower, hinged section. (160mm is larger than almost all of their howitzers and guns.) The big one is the 240mm 2S4, which has two exotic rounds available to it. The first is a laser-guided round; this round was used to devastating effect in Afghanistan during the Soviets' war there. The second is a nuclear round.
When was Sloane Square tube station created?
Sloane Square tube station was created in 1868.
When was Russell Square tube station created?
Russell Square tube station was created in 1906.
How many 6 MM round beads are in a tube?
That depends on the thickness or diameter of the tube.
What people in London call the means of transportation on rails and underground?
The network is called, The Tube, as in: I often take the tube to travel round London, it is quicker than a bus on London's congested roads.
How is a hollow cylinder stronger than a solid cylinder when both have the same mass and length?
if they are short or in tension they are the same, when they bend the hollow tube has a bigger second moment of area and so is stronger to any bending moment
Tube and pipe?
Tube is a made up of rubber, while pipe is a round solid material.
How do you know if your dodge Dakota 2001 is a 4.7l or 5.9l?
The 4.7l has a big square air box on top of the engine. The 5.9 has a round tube that runs over to the air cleaner.
