Question

why the meniscus of the liquid is curved in the measuring cylinder?

Answer 1

Answer:

HOPE IT'S HELPFUL

Explanation:

Concave meniscus is formed. Water is made up of polar molecules, which have positively and negatively charged ends. 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. Glass molecules also happen to be polar. 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.
