What is a test tube bubble called after the measurements of liquid is poured in?
The bubble is called a meniscus. It is caused by surface tension, and usually appears as a curved surface at the top of the liquid in the test tube. To accurately measure the volume of liquid, the measurement should be taken at the bottom of the meniscus.
What is the source of liquid droplets seen on the inner upper side of the test tube during the heating process?
The liquid droplets on the inner upper side of the test tube are likely due to condensation. As the test tube is heated, the air inside expands and rises, coming into contact with the cooler upper side of the test tube, causing it to condense into droplets.
What is the chemical definition of meniscus?
It is from the Greek meaning crescent. When you measure the volume of water (or similar liquid) in a measuring cylinder, if you look carefully you will notice the surface water level is not perfectly flat. It will be curved, this is called the meniscus. To accurately measure the volume you must look at the meniscus at eye level and take the reading at the bottom of the meniscus. The meniscus occurs because water is attracted to the glass/plastic. All equipment that is intended to measure volume will take into account the meniscus, as long as you take your reading with the meniscus at eye level. The measurement must be done at eye level in order to ensure no parallax error. NOTE mercury's meniscus is convex rather than concave, as it is not attracted the glass/plastic.
What is the effect of change the length of tube input liquid in surface taunting?
Changing the length of the input tube for a liquid in surface tension affects the rate at which the liquid flows. A longer tube may increase the flow rate as there is higher pressure due to increased height. This can lead to faster filling or emptying of the container.
Why does meniscus of water in glass curves upwards?
The meniscus of water in a glass curves upward due to surface tension. Water molecules are more attracted to the glass than to each other, causing them to climb up the sides of the glass. This creates a concave meniscus shape.
What does the word menicus?
It seems like "menicus" might be a misspelling. Did you mean "meniscus," which is the curved upper surface of a liquid in a tube?

What is a spaced figure with two bases and one curved surface called?
sounds like a tube to me...
Why does liquid rise in a capillary tube?
Liquid rises in a capillary tube due to capillary action, which is the result of adhesive and cohesive forces between the liquid and the tube. Adhesive forces between the liquid and the tube's surface cause the liquid to be attracted to the tube, while cohesive forces within the liquid molecules help pull the liquid up the tube against gravity.
What liquid is in the upper part of the test tube when you mix water and oil?
oil
State two types of meniscus shape?
The two types of meniscus shape are concave and convex. Concave meniscus has a curved surface where the edges dip below the center, like in a test tube. Convex meniscus has a curved surface where the edges rise above the center, like in a droplet of water on a surface.
Why does a liquid rise in a capillary tube?
This is due to Surface Tension. The molecules/atoms of the liquid are atrracted by the particles of the solid and thus the liquid rises in the capilliary tube.
Law of lower and upper meniscus levels in determining liquid solution?
In measuring liquids using graduated cylinder, there are two things to consider. 1.) CLEAR LIQUID and 2.) COLORED LIQUID (as we may say) In identifying the volume of CLEAR LIQUID (e.g. plain water, oil, alcohol, etc.), THE LOWER MENISCUS is read. For the COLORED LIQUID (e.g. soy sauce, ketchup, etc. ) the upper meniscus is get, since there is only one meniscus there.. (meaning there is no upper & lower meniscus.)

What is quincke 's method?
Quincke's method is a technique used to determine the surface tension of a liquid by measuring the maximum height to which the liquid rises in a capillary tube. It involves carefully introducing the liquid into the tube and allowing it to rise due to capillary action until it reaches equilibrium. The surface tension can then be calculated using the measured height and the properties of the liquid and the tube.
