Name the three states of matter
Solids have a definite shape and volume. Liquids take the shape of the container they are in. Gases have neither a definite shape nor volume.
Solids, Liquids and Gases
Solid: A solid is a state of matter where the particles are closely packed together and held in a fixed position, allowing it to maintain its shape. Liquid: A liquid is a state of matter where the particles are held together but can still move around each other, allowing it to take the shape of its container. Gas: A gas is a state of matter where the particles are spread out and free to move around each other, allowing it to expand to fill its container.
Which state of matter does not keep its shape?
The particles in a gas move faster than the particles in a liquid, which move faster than the particles in a solid. When a gas turns into a liquid, it is called condensation. When a liquid turns into a gas, it is called evaporation. Most of the Earth’s atmosphere is composed of two gases: nitrogen and oxygen.
Did you know?
When matter changes from one phase to another, its physical properties can change dramatically. Gases can be compressed into liquids, and solids can be melted to become liquids. Changes of phase are often accompanied by changes in temperature, pressure, and volume.
Changes in Matter with Changes in Phase
What are the differences between solids, liquids and gases?
What are some examples of physical changes that occur when a solid melts to form a liquid or when a liquid evaporates or boils to form a gas?
How do the particles in solids, liquids, and gases differ in terms of their arrangement and movement?
How do the arrangement and motion of particles change when a solid melts to form a liquid?
