What is meniscus ? why is it necessary to know about it when measuring liquids quizzlet?

AlekseyPX

The downward or upward curve at the surface of liquid in a container is said to be the meniscus of the liquid, which occurs due to the surface tension. This curve can be concave or convex depending on how the molecules of liquid interact with surface of the container. The reading of the meniscus should always be done at the eye-level.

When the particles of the liquid are more attracted to the container than to each other then a concave meniscus occurs whereas when the particles of the liquid are more attracted to each other than to the container then a convex meniscus occurs.

The bottom of the curve will be read for a concave meniscus and for convex meniscus, the top of the curve gives the correct reading of the volume of liquid.

When you have a two-layer mixture of water and tert-butyl methyl ether, what physical property of these liquids assures you that

mash [69]

Answer:

The density.

Explanation:

The density is an intensive property of fluids, defined as mass divided by volume.

This property is directly related to the intermolecular forces that are present in the substance: the stronger the intermolecular forces, the higher the density will be, and viceversa. Therefore, organic fluids usually have lower densities than water, because the intermolecular forces in organic fluids are not as strong as in the intermolecular forcer in water (water has very stable hydrogen bonds, whereas organic fluids have van der Waals, weaker than hydrogen bonds).

The liquid that has the lower density will be the the liquid that is on the top layer. In this case, the organic compound tert-butyl methyl ether will be on top of water.
