11.1: A Molecular Comparison of Gases, Liquids, and Solids. The state of a substance depends on the balance between the kinetic energy of the individual particles (molecules or atoms) and the intermolecular forces.
The heat added at the melting point is used to change the particles from a well-arranged form in the solid to an irregular arrangement in the liquid phase. This process is called the melting of solid. Heat of fusion ( ... 4 th step – boiling of liquid water, multiply the heat of vaporization with the amount of the substance:
The attractive forces between particles in a liquid are weak enough to let the particles move around each other but strong enough to keep them from flying apart. Characteristics of Liquids. Liquids have a definite volume but not a definite shape. The volume of a liquid can be measured and generally is expressed in units of liters.

Particles in liquids and gases move from one location to another. For example – 1. We can smell the food being prepared in the kitchen from a far because the tiny particles of food vapour mix with the air and move in all directions continuously through the process of diffusion. 2. A few drops of ink (potassium permanganate) are evenly ...
All liquids have a certain portion of their particles having enough energy to enter the gas phase, and if these particles are at the surface of the liquid, they do so (Figure 10.5 "Evaporation"). The formation of a gas from a liquid at temperatures below the boiling point is called evaporation The formation of a gas phase from a liquid at ...

The liquid's molecule particles absorb heat energy in order to repel each other's forces. All of the liquid has turned into the gas at point E. As the heating progresses past E, the gas's temperature rises. Cooling Curve. Condensation is a physical transition from a gas to a liquid, and freezing is a transition from a liquid to a solid.
Gases, liquids and solids are all made up of microscopic particles, but the behaviors of these particles differ in the three phases. The following figure illustrates the microscopic differences. ... Liquids and Solids and the Microscopic Explanation for the Behavior; gas: liquid: solid: assumes the shape and volume of its container
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 of the liquid are drawn up above the surface level of the liquid at the edges where they are in contact with the sides of the container. The combination of cohesive and adhesive...
All liquids have a certain portion of particles with enough energy to enter the gas phase, and if these particles are at the surface of the liquid, they do so (Figure (PageIndex{1})). The formation of a gas from a liquid at temperatures below the boiling point is called evaporation.
Liquids are made up of very small particles (atoms, molecules, and/or ions). The particles that make up a liquid: are close together with no regular arrangement, vibrate, move about, and slide past each other. The following figures show the microscopic behavior of the atoms in liquid argon and the molecules in liquid bromine and liquid water.
Steps to Understanding Particle Arrangement and Motion in a Liquid. Step 1: Look at the location of the particles.Liquids have a fixed volume and take the shape of their container. Step 2 ...
All liquids have a certain portion of their particles having enough energy to enter the gas phase, and if these particles are at the surface of the liquid, they do so (Figure 10.6 "Evapouration"). The formation of a gas from a …
Liquids have surface tension, which leads to wetting. Although liquids are common on Earth, this state of matter is relatively rare in the universe because liquids only exist over a narrow temperature …
Explore the basics of states of matter with interactive simulations in a game-like environment on PhET.
The kinetic-molecular theory is a theory that explains the states of matter and is based on the idea that matter is composed of tiny particles that are always in motion.The theory helps explain observable properties and behaviors of solids, liquids, and gases. However, the theory is most easily understood as it applies to gases.
Particle Arrangement in Liquids. In liquids, the particles are near each other, but not tightly packed. The particles in a liquid are able to slide past each other. This allows for the movement of particles throughout the liquid. The looser arrangement of particles is what allows liquids to take on the shape of their container.
Table 11.3 lists values of γ γ for some liquids. For the insect of Figure 11.25(a), its weight w w is supported by the upward components of the surface tension force: w = γL sin θ w = γL sin θ, where L L is the circumference of the insect's foot in contact with the water. Figure 11.26 shows one way to measure surface tension. The liquid film exerts a force on the …

The particles comprising liquids can be molecules or atoms depending on the chemical nature of the substance. The general characteristics of a liquid are the same irrespective of its composition (molecules versus atoms) but hydrogen bonding can increase the attractive forces between molecules making a liquid flow less easily.
Despite stronger attractive forces, molecules in liquids can still move freely about one another, and so the liquids can flow or be poured. When liquids are further cooled, the kinetic energy reduces to a point where the particles almost stop moving due to the strong intermolecular forces and can only vibrate at their fixed position.
The particles of a liquid have enough energy to break free of some of the forces of attraction between the particles. So particles in liquids can move around and can move over each other, allowing ...
Solids and liquids have particles that are fairly close to one another, and are thus called "condensed phases" to distinguish them from gases. Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid ...
