how are liquids described in terms of shape and volume

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent .. Equivalently, this force can be described in terms of energy: there is a fixed amount of energy associated .

Like the particles of a solid, particles in a liquid are subject to intermolecular attraction; however, liquid particles have more space between them, so they are not fixed in position. The attraction between the particles in a liquid keeps the volume of the liquid constant. The movement of the particles causes the liquid to be variable in shape. Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume. The limited amount of space between particles means that liquids have only very limited compressibility.

Solids and liquids are collectively called condensed phases because their particles are in virtual contact. The two states share little else, however. In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume. Most solids are hard, but some like waxes are relatively soft. Many solids composed of ions can also be quite brittle. Solids usually have their constituent particles arranged in a regular, three-dimensional array of alternating positive and negative ions called a crystal.

Liquids, because they flow, can occupy whatever shape their container has, so they do not have a fixed shape. Because the particles in liquids are very close together barely further apart than in solids liquids do not easily compress, so their volume is fixed. Gases can also flow, so occupy the shape of their whole container. They do not have a fixed shape. Because the particles in gases are much further apart than in liquids or solids, they can be squeezed closer together. Gases therefore can be compressed or expanded. They do not have a fixed volume.

Chapter 1 Chapter 1: The Chemical World 1. Water can take many forms. The state the water is in depends upon the temperature. Each state solid, liquid, and gas has its own unique set of physical properties. Matter typically exists in one of three states: solid , liquid , or gas.

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. 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. 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. A distinctive property of the liquid state is surface tension , leading to wetting phenomena.



Properties of Matter: Liquids

The movement of particles in solids, liquids, and gases.

Learn more about this. Recognize that matter is composed of discrete units called atoms and atoms are composed of sub-atomic particles called protons, neutrons, and electrons. Solid is the state in which intermolecular attractions keep the molecules in fixed spatial relationships. Liquid is the state in which intermolecular attractions keep molecules in proximity, but not in fixed relationships. Gas is the state in which molecules are comparatively separated and intermolecular attractions have relatively little effect on their respective motions.

This chapter begins the first where we will look at matter on a microscopic scale. Matter is made of small particles of atoms or molecules. There are three common states of matter, solid, liquid and gas. A gas and a liquid will change shape to fit the shape of their container. A gas will change volume to fit the volume of the container. In general, solids are denser than liquids, which are denser than gases. The particles in the solid are touching with very little space between them.
