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. Figure (PageIndex{2}): The formation of a spherical droplet of liquid water minimizes the surface area, which is the natural result of surface tension in liquids. from Wikipedia.

The blue particle in the bulk of the liquid experiences intermolecular forces from all around, as illustrated by the arrows. However, the yellow particle on the surface does not experience any forces above it because there are no particles above it. This leads to an imbalance of forces, called surface tension.

The physical properties of a substance depends upon its physical state. Water vapor, liquid water and ice all have the same chemical properties, but their physical properties are considerably different. In general covalent bonds determine: molecular shape, bond energies, chemical properties, while intermolecular forces (non-covalent bonds) …

Random particle motion in liquids and gases is a difficult concept for students to appreciate. When asked, "Why don't gas particles fall to the bottom of a vessel?" only about 50% of students thought that the particles were in constant motion. Students stated that particles were forced apart (by heat acting as a substance) when gases were ...

This describes the liquid state. 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. Liquids have the following characteristics:

As was the case for gaseous substances, the kinetic molecular theory may be used to explain the behavior of solids and liquids. In the following description, the term particle will be used to refer to an atom, molecule, or ion. Note that we will use the popular phrase "intermolecular attraction" to refer to attractive forces between the particles of a …

The liquid system transports the particle and focuses the particle stream at the measuring point. Entering particles are injected into the axis of a cylindrical laminar-flow sheath. The particle-and-sheath stream is funneled and accelerated into a narrow linear particle flow (this is the hydrodynamic focusing increasingly used in microfluidics

A colloid is also a heterogeneous mixture, but the particles of a colloid are typically smaller than those of a suspension, generally in the range of 2 to about 500 nm in diameter. Colloids include fog and clouds (liquid particles in a gas), milk (solid particles in a liquid), and butter (solid particles in a solid).

Particles in a liquid have more energy than in a solid, so they are further apart and less organized (more random). Examples of liquids include water, juice, and vegetable oil. Gas. A gas is a state of matter lacking either a defined volume or defined shape. Like a liquid, a gas takes the shape of a container.

Colloids and suspensions both consist of insoluble particles in a liquid. In a colloid, the miniscule insoluble particles are distributed in a liquid and won't separate. And a suspension, on the other hand, is a liquid that contains larger insoluble particles that will eventually separate. Milk is a useful example of the difference between ...
