Water deserve to take numerous forms. At low temperatures (below \(0^\texto \textC\)), that is a solid. As soon as at "normal" temperature (between \(0^\texto \textC\) and also \(100^\texto \textC\)), it is a liquid. While in ~ temperatures over \(100^\texto \textC\), water is a gas (steam). The state thatwater is in depends upon the temperature. Every state has actually its very own unique set of physics properties. Matter commonly exists in one of three states: solid, liquid, or gas.

You are watching: Liquids have a definite shape and volume

Plasma: A fourth State that Matter

Technically speaking, a 4th state of matter called plasma exists, however it does no naturally take place on earth, so we will certainly omit the from our examine here.

Liquids

If the corpuscle of a substance have enough power to partially get over intermolecular interactions, then the particles deserve to move around each various other while remaining in contact. This describes the liquid state. In a liquid, the particles are still in close contact, therefore liquids have actually a definite volume. However, since the particles have the right to move about each other rather freely, a liquid has actually no definite shape and takes a shape dictated through its container.

Liquids have the complying with characteristics:

No definite form (takes the form of the container). Has definite volume. Corpuscle are complimentary to relocate over every other, however are still attracted to every other.

A familiar liquid is mercury metal. Mercury is one anomaly. The is the only metal we recognize of that is liquid at room temperature. Mercury additionally has an capacity to rod to itself (surface tension)—a residential or commercial property that every liquids exhibit. Mercury has actually a reasonably high surface ar tension, which makes it very unique. Here you see mercury in its typical liquid form.



Example \(\PageIndex1\)

What state or states of issue does each statement, describe?

This state has actually a definite volume, but no identify shape. This state has actually no identify volume. This state allows the individual particles to move about while remaining in contact.

Solution

This statement explains the liquid state. This statement describes the gas state. This statement defines the fluid state.
