A liquid is
a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure
. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.
What is a liquid in science?
The liquid state of matter is
an intermediate phase between solid and gas
. … Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume. The limited amount of space between particles means that liquids have only very limited compressibility.
What is liquid and example?
A liquid is a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity. … Examples of liquids are
water at room temperature (approximately 20 oC or 68 oF)
, oil at room temperature, and alcohol at room temperature.
What is liquid called?
Liquids and gases are called
fluids
because they can be made to flow, or move. In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container.
What are gases in chemistry?
Gases are
the phase of matter in which particles are usually very far apart from one another, move very quickly
, and aren’t particularly attracted to one another. Because the molecules in a gas are so far apart from one another, gases are much less dense than liquids or solids.
What are the 5 properties of liquid?
- Liquids are almost incompressible. In liquids molecules are pretty close to each other. …
- Liquids have fixed volume but no fixed shape. …
- Liquids flow from higher to lower level.
- Liquids have their boiling points above room temperature, under normal conditions.
What are 10 examples of liquid?
- Water.
- Milk.
- Blood.
- Urine.
- Gasoline.
- Mercury (an element)
- Bromine (an element)
- Wine.
What is liquid explain?
A liquid is
a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure
. … A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds.
What is liquid in simple words?
Liquid is defined as
a substance that is neither a solid nor a gas
. … The definition of liquid is something that has the consistency of water, that is neither a solid nor a gas, or assets that can be turned into cash easily and quickly.
What is liquid class 9th?
Liquid:
Matters which have fixed volume but indefinite shape are
called liquids. For example – milk, water, petrol, kerosene, alcohol, oil, etc. Since liquid can flow, it is also called fluid.
What are the liquid substances?
Liquid, fluid agree in referring to
matter that is not solid
. Liquid commonly refers to substances, as water, oil, alcohol, and the like, that are neither solids nor gases: Water ceases to be a liquid when it is frozen or turned to steam.
What are the 3 properties of a liquid?
- Liquids are almost incompressible. In liquids molecules are pretty close to each other. …
- Liquids have fixed volume but no fixed shape. …
- Liquids flow from higher to lower level.
- Liquids have their boiling points above room temperature, under normal conditions.
Why is liquid incompressible?
The amount of space (volume) the liquid occupies does not change (actually the volume does change but the change is very tiny). … Liquids are always considered to be incompressible fluids, as
density changes caused by pressure and temperature are small
.
What are the 5 characteristics of gas?
- Low Density. Gases contain scattered molecules that are dispersed across a given volume and are therefore less dense than in their solid or liquid states. …
- Indefinite Shape or Volume. Gases have no definite shape or volume. …
- Compressibility and Expandability. …
- Diffusivity. …
- Pressure.
What is gas and example?
Substances that exist in the gaseous phase are commonly referred to as gases. The most common example of a gas is
air
(the air we breathe is a gas). It can also be considered as a mixture of many gases such as nitrogen, oxygen and carbon dioxide.
What are the 4 properties of gas?
Physical characteristics
Because most gases are difficult to observe directly, they are described through the use of four physical properties or macroscopic characteristics:
pressure, volume, number of particles
(chemists group them by moles) and temperature.
