Solid, Liquids & Gases

• The particles in solids are close together with strong forces between them.
• Solids have a fixed volume and shape
• Solids vibrate around fixed positions
• The particles are packed very closely together in a fixed and regular pattern.
• They have a high density
• In liquids, the particles are closer than those in gases but still move freely past one another.
• Liquid is a state of matter that has no definite shape or size but takes the shape of its container.
• Liquid molecules are attracted to other liquid molecules by intermolecular forces (IMF).
• Liquids have no fixed shape and can flow
• They have a fixed volume
• They have a lower density than solids
• Liquids have weak forces of attraction
• They have a lower density than solids
• Gas particles move very quickly and randomly.
• The particles in gases are far apart from one another.
• There is little or no force between the gas particles.
• A gas has no definite shape or volume.
• Gases can be compressed into smaller volumes by applying pressure.
• There is no structure to the arrangement of gas particles.
• Gases can be compressed into smaller spaces by applying pressure to them.
• Gases have no density
• In solids, the atoms/molecules vibrate around fixed positions within a regular pattern called a lattice.
• Solids have high densities because they are packed tightly together with strong forces holding them in place.
• The forces between molecules are strong enough that they do not move past one another.
• Solids cannot flow like liquids because their particles are held together too strongly.
• The particles in liquids are close together but not as closely packed as those in solids.
• Liquid molecules move freely past one another without any overall movement or flow.
• Gases contains particles that collide which increases pressure
