Answer:
Examples of Solids
Solids are a form of matter that has a definite shape and volume.
Gold
Wood
Sand
Steel
Brick
Rock
Copper
Brass
Apple
Aluminum foil
Ice
Butter
Examples of Liquids
Liquids are a form of matter that has a definite volume but no defined shape. Liquids can flow and assume the shape of their container.
Water
Milk
Blood
Urine
Gasoline
Mercury (an element)
Bromine (an element)
Wine
Rubbing alcohol
Honey
Coffee
Examples of Gases
A gas is a form of matter that does not have a defined shape or volume. Gases expand to fill the space they are given.
Air
Helium
Nitrogen
Freon
Carbon dioxide
Water vapour
Hydrogen
Natural gas
Propane
Oxygen
Ozone
Hydrogen sulfide
Phase Changes
Depending on the temperature and pressure, the matter may transition from one state into another:
Solids may melt into liquids
Solids may sublimate into gases (sublimation)
Liquids may vaporize into gases
Liquids may freeze into solids
Gases may condense into liquids
Gases may deposit into solids (deposition)
Increasing pressure and decreasing temperature forces atoms and molecules closer to each other so their arrangement becomes more ordered. Gases become liquids; liquids become solids. On the other hand, increasing temperature and decreasing pressure allows particles to move father apart. Solids become liquids; liquids become gases. Depending on the conditions, a substance may skip a phase, so a solid may become a gas or a gas may become a solid without experiencing the liquid phase.
