can a gas change shape?

A gas is a substance with no definite volume and no definite shape. Solids and liquids have volumes that do not change easily. A gas, on the other hand, has a vol- ume that changes to match the volume of its container. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid.

Temperature, pressure, volume and the amount of a gas influence its pressure.

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.

A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape.

The shape of molecules depends on hybridization, structural geometry and presence of lone pairs on the central atom. ... Also due to the presence of lone pair would be distorted due to the electron dense cloud of the lone pairs. So the shape of XeF4 would be square planar rather than tetrahedral.

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.

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.

The shape of your hair reflects the shape of the molecules of which it is made. ... The disulphide bonds can only be broken with heat (as happens in 'permanent waving' hair treatment), but hydrogen bonds are affected by water, so the individual molecules can change their shape temporarily when wet.

Gas Composition The amount of space between the molecules in a gas can change easily. If a rigid container—one that cannot change its shape—has a certain amount of air and more air is pumped in, the volume of the gas does not change.

Gas expands to fill the shape and volume of its container. For instance, the steam that comes out of a hot teakettle, making the whistle sing, is water in the form of a gas. Heat causes substances to change their state because, when heated, the molecules within the substance to move around faster.

Characteristics of Liquids Liquids have definite volume, but indefinite shape. They are free to form droplets and puddles when they are not inside a container. When a liquid is inside a container, it will take its shape. Unlike gases, a liquid will not change its volume to spread out and completely fill a container.

matter can exist in one of three main states: solid, liquid, or gas. Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. ... Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.

2) Liquids – have no definite shape but have a definite volume, and they are not easily compressible. ... 3) Gases – a gas has no definite shape, it takes the shape of the container that holds it. Gases are easily compressible. Molecules are separated by distances that are large compared with the size of the molecules.

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.

A gas does not have a definite mass. ... 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.

Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density.
