Filtration is a physical, biological, or chemical procedure that separates solid matter and fluid from a mixture with a filter medium with a complex formation through which only fluid can pass. Solid particles that cannot pass through the filtered method are described as being oversized, and the fluid that goes through is called the filtrate. Oversized particles may form a filter cake on top ...

A mixture occurs when two or more substances are put together; however, each item retains its own chemical identity and does not create a reaction. Some examples of mixtures are Flour and sugar, and marbles and salt. Several types of mixtures are classified under two major categories ranked as heterogeneous or not uniform throughout and homogeneous, which have the same ...

Polar molecules occur when two atoms do not engage equally with electrons in a covalent bond and dipole forms. Part of the molecule brings small positive charges. The other part delivers small negative charges, occurring when there is a discrepancy between electronegativity or a table to predict whether atoms are likely to form polar covalent bonds when molecules share electrons.
In a ...

Atmospheric pressure is also known as barometric pressure, and it is the pressure within the atmosphere of the earth. The amount of atmospheric pressure a human body can take depends on what the person might be doing. Divers tend to maintain increasing pressure as they fall, which can limit how deep you can go.
If the diver breathes the natural air, nitrogen’s narcotic effects ...

The amount of matter in an object is referred to as its mass, and the mass of an object is one of the variables determining its weight, and it is a different property. An object’s mass remains constant, even when there is no gravity.
Mass is both a physical body property and a measure of its resistance to acceleration when a net force is applied. An object’s mass also ...

If you want to separate iron filings from talc powder, you can use an iron magnet. First, you must put your mixture in place, and then, you move your magnet about on the mixture, which will automatically separate the iron filling from the talc powder. Other methods can be employed if the content has more than one element.
For example, suppose the mixture contains filling, powder, and ...

The opening of sodium channels causes an excitatory postsynaptic potential. When sodium channels are open, the electrochemical gradient drives sodium to come into the cell. When sodium gives its positive charge into the cell, its membrane potential becomes more positive or depolarized.
This depolarization raises the likelihood a neuron will be able to come to the action capability; ...
