That is called the 'Meniscus.'
The name of the curve is the "meniscus".

the meniscus
The meniscus is the curve at the liquid's surface. It is produced in response to the surface of the container or another object.
A graduated cylinder is used for measuring the Volume of different things such as irregular objects. It uses the unit ml. It has a miniskus FYI that is when you use water and if you look closely you can see it curve at the top. You measure the miniskus a the bottom of the Curve. Also to find the Volume of an irregular object you first measure the water (starting volume) then place the Object in it and you will have your ending volume. then subtrct the difference from the starting volume and the ending and you will have your volume in ml.
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.
at the bottom of the curve there are two miniscus(curves) in all liquids present in cylinders.when a coloress liquid is present then we see the lower miniscus but when we see colored fluid we see the upper miniscus.
A graduated cylinder is used to measure liquid volume in milliliters, mL. When you place a liquid into a glass graduated cylinder, you will see that the "line" at the top of the column of liquid is actually curved downward. This is called the meniscus. When you measure the liquid volume, you record the volume in mL at the bottom of the meniscus.
graduated cylinder
The special construction is that it has measurements on the side which you can see the liquid transparently ...

no, a balance is used to measure the mass of an object. to find the volume of a liquid, you would put it in a graduated cylinder and see the number it goes up to.
