What is the curve at the top of a liquid?

What is the curve at the top of a liquid?

What is Meniscus? The meniscus of a liquid is the upward or downward curve seen at the top of a liquid in a container. The nature of curve whether upward (convex) or downward (concave) depends on the surface tension the liquid and its adhesion capacity to the wall of the container.

What do you call a curved upper surface of water that commonly appears when using a graduated cylinder?

The water in a cylinder will form a curve called the meniscus 3. Your eye should be level with the top of the liquid 4. Find the bottom of the curved meniscus in the water.

What is the name of the curve you see at the top of a liquid in volume measuring devices?

meniscus
It’s called a “meniscus.” And this word comes from a word that means crescent. Looking at the crescent shape of this surface, we can see why that’s so. The fact that liquids in measuring cylinders form a meniscus impacts how we measure the volume of those liquids.

What is the top of liquid called?

D. Updated October 02, 2019. The meniscus is the curve seen at the top of a liquid in response to its container. The meniscus can be either concave or convex, depending on the surface tension of the liquid and its adhesion to the wall of the container.

What do you call a curved upper surface of the liquid in the tube?

The meniscus is the curve caused by surface tension in the upper surface of a liquid. It can be either convex or concave. Conversely, a concave meniscus occurs when the molecules of the liquid are attracted to those of the container, causing the surface of the liquid to cave upwards.

Is the curved upper surface of liquid in a container?

What do you call the curved upper surface of water that commonly appears using a graduated cylinder b describe what causes this?

Again, since polar molecules like to stick together, the water in a glass tube will actually tend to stick to the sides of the tube! 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 surface of a liquid curved?

The meniscus is the curve caused by surface tension in the upper surface of a liquid. It can be either convex or concave. A convex meniscus occurs when the molecules have a stronger attraction to each other (cohesion) than to the material of the container (adhesion), causing the surface of the liquid to cave downward.

What is a curved surface in a graduated cylinder called?

The Meniscus When observing a volume of a liquid in a graduated cylinder, graduated pipette, or buret, read the point on the graduated scale that coincides with the bottom of the curved surface of the liquid. The curved surface of the liquid is called the meniscus.

What is lower and upper meniscus?

A concave meniscus curves downward; if you are looking down from the top, it curves away from you, like the opening of a cave would. In contrast, a convex meniscus curves upward; if you are looking down into the container, the meniscus curves toward you.

What is upper meniscus?

The meniscus (plural: menisci, from the Greek for “crescent”) is the curve in the upper surface of a liquid close to the surface of the container or another object, caused by surface tension. It can be either concave or convex, depending on the liquid and the surface.

Why there is curve in liquid?

Since opposites attract, the positive sides attract the negative sides, and all of the molecules stick to one another. 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.
