Liquid State of Matter:

Liquids are one of the states of matter alongside solids, gases and plasma. The main difference between each of these states of matter emanates from the nature of their particles.

Think of a particle as the smallest part that makes up anything.

For instance, by grinding a sugar cube, we will expose each of it's constituent particles.

Please read on Solids and their Characteristics here.

In another instance; whenever we cook (let's say a soup or stew), we will likely expose the particles of a maggi cube by grinding it before addition into our soup or stew. The reason why we do this is to separate and expose the constituent particles that make up the maggi cube so they can easily dissolve into our soup.

Regarding the above instances, if you can take out a single (smallest) particle from the grinded sugar, then, such sugar particle can be considered as an atom of the sugar.

Similarly, each of the (single) particle that dissolves into the soup make up the atoms of the maggi.

By definition, an atom is the smallest part (or particle) of a substance that can take part in a chemical reaction.

Note: Understanding the concept of matter, atoms and particles will prove useful regarding the states of matter.

Please read on the Concept of Matter here.

The terms atom and particle will be used interchangeable in order to help you better understand liquids (as a state of matter).

Liquids have spaces between their atoms; thus its particles can exhibit some degree of movement.

The particles of a liquid are loosely packed together.

The image below shows the loosely arranged particles (atoms) in a liquids:

Spaces are present between the liquid particles because their atoms are held by a very weak force. These spaces are large enough to make the atoms move or flow. As a result, you can put you finger through a liquid and pull it out again.

Note: A liquid cannot be handed to another person without the help of a container, else, it pours off. This is so because their atoms are loosely packed together.

A liquid will therefore always assume the shape of it's container.

Even in lakes and rivers, the bank, river bed (or bottom) and the shore forms its container or boundary.

Please read on Gases and their Characteristics here.

The density of liquids will also depend on the atoms they are composed of; for instance, 10kg of water will not weight the same as 10kg of red oil because their constituent atoms are different. (In the case of water, it's constituent atoms are hydrogen and oxygen respectively).

You can read more on the Density of various Substances here.

Note: The particles that make up a liquid can still be compressed such that they become more closer to themselves. The refrigerator is an example of a technology that compresses liquid particles. (This is how water is transformed into ice).

Please read on the Mechanism of Action in a Refrigerator here.

Characteristics of Liquids

  1. They assume the shape of the container.
  2. Their particles are loosely packed together, hence they can be slightly compressed.
  3. Their particle possesses low energy for movement and rotational motion, hence they can flow to an extent.
  4. They have fixed volume but no fixed shape. Liquids will generally assume the shape of their containers.
  5. Under normal conditions, they have boiling points above room temperatures.

Amazing facts in Chemistry

The only letters that failed to appear on the periodic table are letters:

J     &     Q

Gold and copper are the only two non-silvery colored metals.

Please read some interesting facts about gold here

Copper is the only metal that is naturally antibacterial. This is why you would see some children utilize 'copper' water bottles in schools

Water actually freezes faster when it’s warm than when it’s cold

Most element in their pure state exists physically in different forms. For instance, pure carbon can exist as both diamond and graphite. This phenomenon is called allotropy.

Please read on modification of Dalton's atomic theory here.

If you pour a handful of salt into a full glass of water, the water level will go down rather than overflowing the glass.

Similarly, if you mix half liter of water and half litre of alcohol, the total volume of the liquid will be les than one litre
