What is gaseous state Class 11?
They do not have definite shape and take up the shape of the container. They do not possess definite volume due to weakest intermolecular forces. They are not rigid. They are easily compressible due to excess space between the particles of gas which compresses on applying pressure.
What is gaseous state in chemistry?
Gas is the state of matter in which the particles are far apart, fast-moving and not organized in any particular way. The gaseous state features very small attractive forces between the gas particles, which are separated from each other by relatively greater distances when compared to liquids and solids.
What is a gaseous phase?
gaseous phase (plural gaseous phases) (physics) One of the three fundamental structural phases of matter in which the thermal mobility of molecules or atoms is strong enough to permit their free motion, significantly exceeding the cohesive force.
What is the gaseous state of an atom?
A gas is one of the three classical states of matter (the others being liquid and solid). A pure gas may be made up of individual atoms (e.g. a noble gas or atomic gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
Which is a gaseous substance?
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 is gaseous state Class 9?
What is gaseous mean in science?
gaseous Add to list Share. Describe the form of a substance that’s not solid or liquid as gaseous. Gaseous matter will expand to fit an entire container, and it has no volume and no shape.
Is the gaseous phase of water?
Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere.
What is gaseous form?
Definition of gaseous 1 : having the form of or being gas also : of or relating to gases. 2a : lacking substance or solidity.
Where is the gaseous state?
The gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases.
What are the formulas for gaseous state Class 11?
Here is the list of all Gaseous State Class 11 Formulas. This formula list is very important to revise before your JEE Main, Advanced or NEET Exam. Here, R = Temp. on unknown scale. P 1 = n 1 R T v, P 2 = n 2 R T v, P 3 = n 3 R T v and so on. Total pressure = P 1 + P 2 + P 3 + … …. Partial pressure = mole fraction X Total pressure.
What are the properties of a gaseous state?
The gaseous state features very small attractive forces between the gas particles, which are separated from each other by relatively greater distances when compared to liquids and solids. It is important to note that substances that exist in the gaseous state do not have any definite volume or any definite shape.
What are the main postulates of kinetic theory of gases?
The main postulates of kinetic theory of gases are as follows: 1.Every gas consists of a large number of very small particles called molecules. 2.The molecules of a gas move haphazardly colliding among themselves and with the walls of the container and change their direction.
What are the names of the pure gases?
These are Helium, Neon, Argon, Krypton, Xenon, Radon, Hydrogen, Nitrogen, Oxygen, Fluorine and Chlorine. These gases are called pure gases. The difference in the intermolecular distances between the particles of solids, liquids, and gases are illustrated below.
