The rise around the edges is called the meniscus, like capillary action this is caused by the adhesion of the liquid molecules to the walls of the container. In a large bore tube like a test tube or graduated cylinder this pulls up the edge and creates a concave meniscus, in a smaller bore tube this actually pulls the liquid toward the top of the tube.
Capillary action. It occurs due to the adhesive forces between the water molecules and the walls of the test tube, causing the water to climb up the tube against the force of gravity.

What happens when you blow over the mouth of a test tube which is half filled with water?
Blowing over the mouth of the test tube will create a decrease in air pressure inside the tube. This decrease in pressure will cause the water in the test tube to rise up due to the higher pressure outside the tube. Ultimately, the water level in the test tube will rise as a result of the change in pressure.
Why hopkinson's test is called heat run test?
Hopkinson's test is often referred to as a heat run test because it involves running the transformer at full load for an extended period to simulate operating conditions and measure temperature rise. The test helps to evaluate the transformer's thermal performance and ensure it can safely handle the heat generated during normal operation.
What are the big test tubes called?
Bigger, fatter test tubes are usually called boiling tubes.
Why is tap water being used as a test substance?
Why is tap water being used as a test substance
What is the name of carbon dioxide gas test?
The test to detect the presence of carbon dioxide gas is called the limewater test. It involves passing the gas through limewater (a solution of calcium hydroxide) and observing a milky white precipitate forming if carbon dioxide is present.
Why sumpners test is called heatrun test?
The temperature rise is not considered in OC & SC tests of transformers.. But in Sumpner's test, temp. rise is considered.. Hence is called "Heat-run test".. Also, the transformers draw only the power req. to supply core & Cu. losses of transformer..

What is the dip in the water in a test tube called?
The dip in water in a test tube is known as the meniscus. It is caused by the surface tension of the water, which causes it to curve slightly at the edges of the container. When measuring liquids in a test tube, readings are typically taken at the bottom of the meniscus.
What causes blue well water?
As a plumber I have found industrial water dye pranks to be on the rise. Otherwise it could be caused by unique chemicals in the ground. Take samples to a lab for test to make sure the water is safe, or potable. A plumber will know who to talk to in your area to test water samples.
What will happen when a inverted test tube is inserted into a measuring cylinder containing water?
As the inverted test tube is inserted into the measuring cylinder containing water, the water will rise up into the test tube due to atmospheric pressure. The level of water inside the test tube will stabilize at a certain height once the pressure inside and outside are balanced. This can be used to measure the volume of the test tube.
What is the main test used for Budd-Chiari Syndrome?
the key test is called hepatic vein catheterization. In this test, a narrow tube is snaked through the body until it reaches the hepatic veins. An instrument at the tip of the catheter can measure the pressure within each segment of the hepatic vein.
How do you raise the anchor in the impossible test water?
You turn the phone upside down and keep tapping the anchor and it will slowly rise up. Then you tap the button underneath
What does it mean don't spill the water on the moron test?
There is a game called "The Moron Test". There is a stage in the game where you have to avoid spilling water out of a fishbowl, I think. I believe it rotates around and you have to rotate your iDevice to keep the water in.
How do you test the porosity of a soil?
To test the porosity of a soil, you can conduct a simple experiment called the water infiltration test. Dig a hole in the soil, pour a measured amount of water into the hole, and then measure the time it takes for the water to infiltrate into the soil. The faster the water infiltrates, the higher the porosity of the soil.
What is the taks test now call?
It is called the star test. It will not be called the taks test anymore, but it will be called the star test.
What are the release dates for America's Test Kitchen - 2000 Rise and Shine Breakfast - 12.3?
America's Test Kitchen - 2000 Rise and Shine Breakfast - 12.3 was released on: USA: January 2012
How does air lock affect a hydrostatic test?
Air can cause a very unsafe rise in pressure as air can be compressed as opposed to water thus the rational for a T&P valve.
