Hint: In the case of a concave meniscus, the correct volume will be read at the bottom of the curve. And in the case of a convex meniscus, the opposite is true and the perfect reading will be at the top of the curve.
Complete step by step answer:
First of all let us discuss what actually a meniscus means. A meniscus is seen in the form of a curve in the surface of a molecular substance like water when it touches another surface. For example, we can think of water as when water sticks to the inside of a glass meniscus is formed there. A meniscus is developed because of surface tension in the liquid and must be read at eye level. The meniscus of a fluid in a test tube is because of the capillary force in the liquid, gas. Solid interface So long as the two fluids are not the similar kind, they will have change in properties even in small amounts and there will always develop a meniscus. Water is having a convex meniscus. This occurs with water and the glass container. A convex meniscus is developed when the molecules have a stronger attraction to each other than to the container. Therefore the correct answer is option B.
Note:
In the case of a concave meniscus, the volume of the liquid in the tube is read from the lower part of the curve. We can notice a 'line' of liquid at the top, creating the curve itself. The bottom of the curve is actually the lower side of this line.
