What is the movement of water up a narrow tube due to attractions with the surface of the tube called? capillary action meniscus

Shtirlitz [24]

The attraction mediated flow of water in the narrow tube has been termed as Capillary action. Thus, option A is correct.

The process of flowing up of liquid with the attraction force between the molecules and the surface has been achieved with the surface characteristics.

<h3>Movement of water in a narrow tube</h3>

The surface has the force of attraction with the flowing liquids in the sample. It results in the increased surface interaction, and the liquid flows up in the tube against gravity.

The movement of the liquid in the water through a narrow tube has been termed as capillary action. Thus, option A is correct.

What is the correct formula for calcium sulfate dihydrate?

Murljashka [212]

Answer:

It is CaSO4.2H2O

Explanation:

Calcium has a valence of 2 because it has only two valency electrons.

Sulphate ( SO4)^2- is a radical with a valence value of 2.

When Calcium combines with sulphate in bonding,

Formular ==>  Ca2(SO4)2

But the 2 cancel out.

Overall formular==> CaSO4

For hydrated, ==> CaSO4.H2O

Describe the differences among primitive, igneous, sedimentary, and metamorphic rock, and relate these differences to their orig

Akimi4 [234]

Answer:

Rocks are the aggregate of minerals. There are three distinct categories of rocks, namely the sedimentary, metamorphic and the igneous rocks.

The sedimentary rocks are formed from the deposition, compaction, and lithification of soft sediments that are transported from one place to another by the agents such as wind, water, and ice. For example, Sandstone and Shale.

The metamorphic rocks are derived from the previously existing sedimentary, igneous or other metamorphic rocks, due to the influence of extremely high pressure as well as temperature conditions. For example, Quartzite and Marble.

The igneous rocks are those rocks that are formed from the cooling and crystallization of magma. For example, Granite and Diorite.

All these three types of rocks are formed by different processes and their mode of origins are also different.
