Be sure to check out our other chemistry worksheets and handouts. Web when a tube of a narrow bore, often called a capillary tube, is dipped into a liquid and the liquid wets the tube (with zero contact angle), the liquid surface inside the tube forms a concave meniscus, which is a virtually spherical surface having the same radius, r, as the inside of the tube. Measure so that the line you are reading is even with the center of the meniscus. Web a graduated cylinder is meant to be read with the surface of the liquid at eye level, where the center of the meniscus shows the measurement line. Web how to take measurements with a meniscus.
Web a meniscus is the curved surface at the top of a column of liquid. This meniscus worksheet is a great way to practice reading the meniscus of. Measure so that the line you are reading is even with the center of the meniscus. Web the meniscus is the curvature, either convex or concave, often observed when liquids are placed into a container.
If the meniscus is convex, take your measurement at the highest point of the curve. To read a meniscus, you first need to see what type of meniscus your liquid forms. It is narrow and cylindrical with markings for volume measurement.

A meniscus is formed because the adhesive and cohesive forces don't balance each other perfectly,so there can be extra pull/push due to the force between the surface of the container and the fluid, which forms.
In a science class, this liquid is usually water or some sort of aqueous solution, and the column is usually a graduated cylinder or a pipet. Web the meniscus is the curvature, either convex or concave, often observed when liquids are placed into a container. To read a meniscus, you first need to see what type of meniscus your liquid forms. Web the long answer: 3.8k views 5 years ago.
Answered nov 20, 2019 at 18:21. This should be in the center of the graduated cylinder. The meniscus in a graduated cylinder forms as a result of the difference in the.
This Meniscus Worksheet Is A Great Way To Practice Reading The Meniscus Of.
Bend down or adjust the height of your gaze so that you're looking straight at the level of the liquid. Take your measurement from the center of the meniscus. Typical capacities of graduated cylinders are from 10 ml to 1000 ml. Almost all liquids have a meniscus but water has the highest surface tension, making its meniscus levels more prominent and suitable for classroom learning.
A Meniscus Is The Curve Formed On The Top Of A Liquid.
To read a meniscus, you first need to see what type of meniscus your liquid forms. Web and since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus. They'll travel up the glass as far as water's cohesive forces will allow them, until gravity prevents them from going further. This should be in the center of the graduated cylinder.
Web Reading A Graduated Cylinderwhen Looking At The Cylinder The Liquid Does Not Create A Flat Line, But It Forms A “U” Shape.
Find the bottom of the curved meniscus in the water. Web feel free to use this worksheet in your classrooms. Web to correctly read a graduated cylinder, the surface at the center of the meniscus must be read, not the top of the ring of liquid clinging to the wall of the graduated cylinder. Along with the volume of liquid, it is also indirectly used to measure the mass of a solid.
Web A Graduated Cylinder, Or Measuring Cylinder, Is Used Mainly In Laboratories Requiring Moderately Precise Volume Measurements.
A meniscus is a fibrocartilaginous tissue. If the meniscus is a concave meniscus, read at the lowest level of the curve. To read the volume of a liquid in a graduated cylinder accurately, the reading must be taken at eye level and at the bottom of the meniscus. If the meniscus is convex, take your measurement at the highest point of the curve.
