Gases are mostly empty space , and this is evident because gases can be easily compressed. It is easy to reduce the volume of a gas as compared to reducing the volume of a solid. ... The gas molecule do not interact with each other except for colliding with each other.
Can gas occupies the space of the container?
Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form.
What do we call an empty space with no gas particles and no pressure?
vacuum . an empty space with no particles and no pressure.
Why do gases take all the space available to them?
Gases take up a lot of space because they lack inter-molecular forces .
How small are gas particles?
The general impression of gas molecules given by these numbers is that they are exceedingly small , that there are enormous numbers of them in even one cubic centimetre, that they are moving very fast, and that they collide many times in one second.
What happens when gas is cooled?
If a gas is cooled, its particles will eventually stop moving about so fast and form a liquid . This is called condensation and occurs at the same temperature as boiling. ... Evaporation is dependent on individual particles gaining enough energy to escape the surface of the liquid and become gas particles.
What is the smallest gas particle?
Atom : The smallest Particle.
Why you can compress gas easily but not liquid?
There is no space between the individual particles, so they cannot pack together. The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles .
Why do gases expand to fill the container class 6?
Answer: Gases are in rapid motion , and they undergo elastic collisions with each other and the walls of the container; that is, momentum and energy is transfered not lost during collisions. Gases expand spontaneously to fill any container (rapid motion).
Can a container of gas be only partly full?
Liquids can only fill the bottom of a container, while gases can fill it entirely . The shape of liquids is very dependent on gravity, while less dense gases are light enough to have a more freedom to move.
What is it called when there are no gas particles in a given space?
vacuum . An empty space with no particles and no pressure is called.... atmospheric pressure. results from the collisions of atoms and molecules in air with objects. decreases.
How can you increase the pressure of a gas?
- Add more gas. More molecules mean more collisions. ...
- Decrease the volume. Less space means less room for the atoms to move in and this will lead to more collisions and more pressure.
- Increase the temperature.
What is the least dense form of matter?
Plasma is the least dense form of matter. Exists at the highest temperatures or the lowest pressure. Plasma occurs at the highest temperature, such as in an atomic bomb blast. It also occurs at the lowest pressure.
Can gasses be compressed?
Gas. The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. ... Gas can be compressed much more easily than a liquid or solid .
Does gas have fixed shape?
Gases don't have a fixed shape or a fixed volume. The particles move around all the time and spread out. This is why a gas fills its container. A gas can be compressed into a very small space – this pushes the particles closer together.
Do liquids fill all available space?
A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Like a gas, a liquid is able to flow and take the shape of a container. ... Unlike a gas, a liquid does not disperse to fill every space of a container , and maintains a fairly constant density.
