Why gas has no definite shape and volume?
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.
Does gasses have a definite volume?
Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy.
Does vapor have shape or volume?
Liquids have a definite volume, but not a definite shape. In a gas, the forces between particles are so weak that the particles no longer cling together. Gases do not have a definite shape or volume. The most common state of matter in the universe is the plasma state.
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.
How the gas and liquified gases are classified?
Liquid matter is made of more loosely packed particles. Particles can move about within a liquid, but they are packed densely enough that volume is maintained. Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed.
What is definite volume of water?
In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
Does a gas have a definite volume?
A gas does not have a definite volume . A gas does not always weigh the same or take up the same amount of space. However, like a liquid, a gas will always take the shape of its container, no matter the size or shape of that container.
What state of matter has a definite volume but no definite shape?
Continuum mechanics. 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.
Does liquid have definite volume?
Liquids. In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
What is definite volume?
Definite volume refers to something which has a consistent, unchanging volume, which in practical terms may mean a static mass and density, or a predetermined shape, either of which will dictate volume. For instance:
