• Boyle's law
• The pressure exerted by a gas is directly proportional to the number of molecules present.
• A gas will expand when heated and contract when cooled.
• Gases have no fixed shape or volume, but they do occupy space.
• When two gases are mixed together, their volumes remain constant until equilibrium is reached.
• Liquids are fluids that take on the shape of their container.
• Matter can be classified as solid, liquid, or gas based on its physical properties.
• Solids have a definite shape and volume.
• Water is an example of a liquid.
• Liquids are fluids that flow slowly and can be poured from one container to another.
