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.

Mercury has its meniscus upward?

If the meniscus of mercury in a glass tube is curved upwards, it indicates that the adhesive forces between mercury and the glass are stronger than the cohesive forces within the mercury. This is due to the high cohesion and adhesive properties of mercury.

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.
