Why is water curved in a graduated cylinder?
Since opposites attract, the positive sides attract the negative sides, and all of the molecules stick to one another. This is why water droplets can form. You can see this at the top of the graduated cylinder, where the water will slightly creep up the sides and form a curve, which is the meniscus.
Why is the meniscus in a graduated cylinder of water concave?
A concave meniscus, which is what you normally will see, occurs when the molecules of the liquid are attracted to those of the container. This occurs with water and a glass tube. A convex meniscus occurs when the molecules have a stronger attraction to each other than to the container, as with mercury and glass.
Why the meniscus is concave up of water in a glass tube?
Why do most liquids have concave meniscus?
Most liquids have concave menisci because the molecules of those liquids are more strongly attracted to the walls of their container than to each other. The liquid ‘sticks’ to the walls instead of lying flat, causing the downward curve.
What is a meniscus in a graduated cylinder?
When a liquid is placed into a graduated cylinder, the surface takes on a curved shape. This curve is known as a meniscus. The graduated cylinder is calibrated so that reading the bottom of the meniscus, when viewed at eye level, will give accurate results.
Why does water curve in a graduated cylinder quizlet?
Theres a concave meniscus, which happens when the water molecules of the liquid are attracted to the container(you see it with water). A Convex meniscus happens when the molecules are more attracted to themselves.
Why does water have a concave meniscus while Mercury has a convex meniscus?
Water meniscus in a glass tube is concave while that of mercury is convex. In case of water, the adhesive forces in the molecules of glass and water are stronger than the cohesive forces in the water molecules. Therefore, the meniscus of water is concave.
Is water concave or convex?
In case of water, the adhesive forces in the molecules of glass and water are stronger than the cohesive forces in the water molecules. Therefore, the meniscus of water is concave.
Which properties of water contribute to the formation of the meniscus quizlet?
Meniscus happen because of adhesion and has to do with waters fairly high surface tension. Water molecules are attracted to other molecules, but since they also like to stick to water molecules, when they touch the glass they cling and others will too. They go up as far as cohesion and gravity allow.
What is a meniscus in chemistry quizlet?
What is a meniscus? A curve in the surface of a liquid substance(such as water) when it touches another material. When reading a volume in a graduated cylinder, it is also important that your eyes are level so that you are not looking at the meniscus from the top or the bottom.
