meniscus
miniscus
The curve on a graduated cylinder is called a meniscus. It occurs due to surface tension between the liquid and the container, causing the liquid to curve at the edges. When measuring volume in a graduated cylinder, the bottom of the meniscus should be used for accurate readings.
curve
The "bottom of a curved line" made by the liquid in a graduated cylinder could be called the "measuring line" or "reference line" in the application of that piece of labratory equipment. The curved surface of the liquid itself is called the meniscus, and we look to the bottom of the meniscus to make our reading as to the volume of the liquid in the graduated cylinder. The liquid in the cylinder "grabs" the sides of the cylinder and "pulls itself up" just a bit, and that creates the curve in the surface of the liquid. And that curve, the meniscus (which is from the Greek word for crescent), leaves us with a problem: where do we "read" the volume marked off by the graduations along the side of the cylinder? And the answer is, "At the bottom of the meniscus."
The liquid curve is called a meniscus.
To read the meniscus in a graduated cylinder when measuring liquid volume, look at the bottom of the curve where the liquid meets the cylinder. Read the measurement at eye level to get an accurate volume reading.
The name of the curve is the "meniscus".
The meniscus of a liquid is read at the bottom of the curve that forms at the liquid's surface in a graduated cylinder or a similar container. To determine the volume of the liquid accurately, it is important to read the measurement at the lowest point of the meniscus.
The meniscus is a curve in the surface of a liquid that is caused by surface tension and by the attraction between the liquid and the sides of the container. The bottom of the meniscus represents the most accurate measurement because the lines of a graduated cylinder are in the middle of the graduated cylinder.
A graduated cylinder is used to precisely measure volumes of liquid. By pouring the liquid carefully into the graduated cylinder and reading the measurement at the bottom of the meniscus (liquid curve), you can accurately measure 55 ml of liquid.
The lower meniscus is important in determining the volume of a liquid in a graduated cylinder because it is the curved surface at the bottom of the liquid level. When measuring volume, the measurement is taken at the bottom of the meniscus to ensure accuracy, as the liquid tends to curve slightly at the edges due to surface tension.
Since the surface of water rises up to the sides of the cylinder, the low point is in the center of the surface. (Volume is assumed unless boiling or melting points are stated)
