Heat, cool and compress atoms and molecules and watch as they change between solid, liquid and gas phases.

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.

2021年9月24日 · All of the changes of state that occur between solid, liquid, and gas are summarized in the diagram in the figure below. Freezing is the opposite of melting, and both represent the equilibrium between the solid and liquid states. Evaporation occurs when a …

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between 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.

Find out what particle arrangements and movements are in solids, liquids, and gases in this BBC Bitesize KS3 physics guide.

2020年10月8日 · Solid: A solid can melt into liquid or sublimate into gas. Liquid: A liquid can freeze into a solid or vaporize into a gas. Gas: A gas can deposit into a solid, condense into a liquid, or ionize into plasma. Plasma: Plasma can deionize or recombine to form a gas.

A sample of matter can be classified as being either a solid, a liquid, or a gas. These three states of matter are distinguished from each other by their observable properties and the underlying particle-level characteristics.

Solid is the state in which matter maintains a fixed volume and shape, liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume, and gas is the state in which matter expands to occupy the volume and shape of its container.

Liquids and solids are often referred to as condensed phases because the particles are very close together. The following table summarizes properties of gases, liquids, and solids and identifies the microscopic behavior responsible for each property.
