What is the curve at the surface of a liquid called?
A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass.
What is it called where you look to measure the volume of a liquid?
We’ve seen in this section that liquid volume is measured in a measuring — also called a graduated — cylinder. And we’ve seen that those cylinders look like this, with volume markings etched into the side of them. Secondly, we saw that liquid in a cylinder forms a curved surface. That’s called a meniscus.
Why liquid surfaces are generally curved?
The meniscus is the curve caused by surface tension in the upper surface of a liquid. Capillary action acts on concave menisci to pull the liquid up, increasing the favorable contact area between liquid and container, and on convex menisci to pull the liquid down, reducing the amount of contact area.
How do you measure volume in chemistry?
The volume of a substance can be measured in volumetric glassware, such as the volumetric flask and the graduated cylinder. Density indicates how much of a substance occupies a specific volume at a defined temperature and pressure.
What does curved surface area mean?
Curved Surface Area- The curved surface area is defined as the area of only curved surface, leaving the circular top and base. Total Surface Area- It is the area of the curved surface as well as the bases.
What is curved surface area of cone?
Curved surface area of a cone = πrl. Total surface area of a cone = πr(l+r) l=√h2+r2.
How can we determine the volume of a liquid with a meniscus that curves upwards?
When it curves upwards it reveals that the liquid has stronger adhesive force than cohesive force. When meniscus of liquid curves upward in a calibrated container the volume of the liquid is determined by reading the values at the bottom of the curving point.
