Curved surface of a liquid?
Meniscus
What is the curved surface of a liquid in a graduated cylinder?
Meniscus.
What is the curved line that forms when water is in a graduated cylinder?
This line is called the meniscus.
What you call the point when a curve changing from concave upward to concave downward?
The point when a curve changes from concave upward to concave downward is called the inflection point. It is the point where the curve transitions from being curved "upwards" to being curved "downwards" or vice versa. At the inflection point, the rate of change of the curve's curvature changes sign.
Explain Why is the surface of water in a graduated cylinder curved?
it is probably called figure it out, it is curved because glass is sticky. When you measure the volume from a graduated cylinder, measure at the bottom of it. It is called the meniscus.
When does the meniscus of a liquid in a glass tube curve downward?
A meniscus is caused by surface tension and It curves down (concave) when the liquid adheres to the container more than to itself, like water and glass. Mercury clings more to itself than glass, so it is curved up (convex)
What is the scientific name for the curved water surface above the rim of a glass?
The curve you see on top of a liquid in a cylinder is called the meniscus and is due to the difference between the attractive force between the liquid molecules themselves and between the liquid molecules and the wall of the cylinder, as well as capillary action. When the molecules of the liquid have a greater attraction to the cylinder wall than to themselves, the meniscus is concave and the surface of the liquid curved downwards. Water drawn up a narrow glass cylinder has a concave meniscus. When the molecules of the liquid have a greater attraction to themselves than to the cylinder wall, the meniscus is convex and curves upwards. Mercury in a glass thermometer or barometer has a convex meniscus.
What is the curved surface of a liquid called?
Meniscus
Why does meniscus of water in glass curves upwards?
Adhesion to the test tube or cohesion of the liquid molecules causes the meniscus to form.
Why is mercury curved upward?
The meniscus (plural: menisci, from the Greek for "crescent") is the curve in the upper surface of a liquid to the surface of the container or another object. 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). This may be seen between mercury and glass in barometers and thermometers. Conversely, a concave meniscus occurs when the molecules of the liquid attract those of the container's, causing the surface of the liquid to cave downwards. This can be seen in a glass of water. One can over-fill a glass with mercury and produce a convex meniscus that rises above the top of the glass, due to the vacuum created with the airtight substance.
