Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around . The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume.
Do gases not have a definite shape?
Gases. If the particles of a substance have enough energy to completely overcome intermolecular interactions, then the particles can separate from each other and move about randomly in space. ... Like liquids, gases have no definite shape , but unlike solids and liquids, gases have no definite volume either.
Does gas have a definite shape?
A gas has neither a definite shape nor a definite volume . Like liquids, gases are fluids. The particles in a gas can move around one another freely. If a gas is released in a closed container, the gas particles will move in all directions and spread apart as they fill the container.
What does not have definite shape but they do have definite volume?
Three states of matter exist – solid, liquid, and gas. Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
Does oxygen have a definite shape?
Like liquids, gases have no definite shape , but unlike solids and liquids, gases have no definite volume either. The change from solid to liquid usually does not significantly change the volume of a substance. ... No definite shape (takes the shape of its container)
Which state of matter has zero Diffusibility?
| List I List II | 1. Have no definite shape, volume or free surface A. Solids only | 2. Are highly compressible and less rigid B. Liquids only | 3. Have a definite volume, no definite shape and are slightly diffusible C. Gases only | 4. Are not compressible and have no diffusibility D. Liquids and gases only |

Does a gas have a definite mass?
Solids are the ones who have rigid structure and which have a definite volume and shape. ... – Therefore, gases take the shape of the container and occupy the complete volume of that particular container. – Thus, the correct answer to this question is that gases have definite mass but no definite volume and shape .
What has little or no attraction between particles?
Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. ... In most cases, there are essentially no attractive forces between particles. This means that a gas has nothing to hold a specific shape or volume.
Why solid matter has definite shape and volume but gas does not?
Solution : (a) Solids have definite shape and definite volume because the molecules in solid are closely packed and in fixed positions. ... (c) Gases do not have a definite shape or volume because the molecules in gases are very loosely packed , they have large intermolecular spaces and hence they move around.
What shape does not follow a definite pattern?
lacking definite form; having no specific shape; formless: the amorphous clouds . of no particular kind or character; indeterminate; having no pattern or structure; unorganized: an amorphous style; an amorphous personality.
In which physical state matter has no definite shape?
Volume: Gas is the state of matter that has no definite shape or volume.
Which states of matter do not have definite shapes?
Four states of matter are solid, liquid, gas , and plasma. Solids have definite shape and definite volume. Gas has no definite shape or definite volume.
What is the hardest state of matter?
As the temperature continues to drop, the matter forms a solid. Due to the solid's low kinetic energy, particles have no “time” to move around, the particles have more “time” to be attracted. Therefore, solids have the strongest intramolecular forces (because they have the strongest attraction).
Does matter Really matter?
Matter is all around you. Matter is anything that has mass or takes up space . If it's made up of atoms or molecules, it's matter! ... Whether its physical state is a solid (ice), a liquid (water), or a gas (vapor), it's still water made up of H 2 O molecules.
Which states softest matter?
Soft materials are materials that can be easily deformed by thermal stresses or thermal fluctuations at about room temperature. Soft materials include liquids , polymers, foams, gels, colloids, granular materials, as well as most soft biological materials.
Which is not a matter?
Non-matter includes the light from a torch , the heat from a fire, and the sound of a police siren. You cannot hold, taste, or smell these things. They are not types of matter, but forms of energy. Everything that exists can be classed as either a type of matter or a form of energy.
