What is the main difference between a solid and a liquid?
Solids flow while liquids don't
Solids have a definite shape, while liquids do not
Liquids have a definite shape, while solids do not
Solids and liquids both have no shape
Solids, liquids, and gases are the three main states of matter. Solids have a fixed shape and volume, like a rock or a toy. Liquids have a definite volume but take the shape of their container, like water in a glass. Gases have no fixed shape or volume and can spread out to fill any space, like the air we breathe. Understanding these states helps us see how different materials behave and change in our everyday lives.
Solid, liquid, and gas are the three basic forms of matter. A solid has a fixed shape and volume, like a block of wood. A liquid has a definite volume but takes the shape of its container, like milk in a cup. A gas has no fixed shape or volume and spreads out to fill any space, like the air in a balloon.
Changing between a solid, a liquid, and a gas involves the processes of melting, freezing, boiling, condensation, sublimation, and deposition. These changes occur due to the addition or removal of heat energy, causing changes in the movement and arrangement of particles.
Solids, liquids, and gases differ in their properties:
Property | Solid | Liquid | Gas |
---|---|---|---|
Shape | Fixed | Takes the shape of its container | No fixed shape, fills any container |
Volume | Fixed | Fixed | No fixed volume, expands to fill space |
Particle Arrangement | Closely packed in a regular pattern | Close together but not in a fixed pattern | Far apart and move freely |
Movement of Particles | Vibrate in place, little movement | Move around each other, allowing flow | Move quickly and freely in all directions |
Examples | Rock, ice, wood | Water, milk, oil | Air, helium, steam |
Understanding the properties of solids, liquids, and gases helps us comprehend how different materials behave. Here are the key properties of each state of matter:
Solids have a fixed shape, liquids have a fixed volume but no shape, and gases have neither fixed shape nor volume.
Yes, solids can melt into liquids when they are heated, like ice melting into water.
Yes, liquids can evaporate into gases when heated, like water boiling into steam.
Yes, gases can condense into liquids when cooled, like steam condensing into water droplets.
When you freeze a liquid, it turns into a solid because its particles slow down and form a fixed structure, like water freezing into ice.
Yes, solids can sublime into gases without becoming liquid first, like dry ice turning into carbon dioxide gas.
Liquids take the shape of their container because their particles can move around each other, allowing them to flow.
Gases fill their container because their particles move very fast and spread out in all directions.
Solids do not flow because their particles are tightly packed and can only vibrate in place, not move freely.
An example of a liquid is water. It flows and takes the shape of its container.

Changing between a solid, a liquid, and a gas involves the processes of melting, freezing, boiling, condensation, sublimation, and deposition. These changes occur due to the addition or removal of heat energy, causing changes in the movement and arrangement of particles.
Melting: Solid to Liquid
When a solid is heated, its particles gain energy and start vibrating more vigorously. At a certain temperature, known as the melting point, the particles have enough energy to break free from their fixed positions. The solid becomes a liquid.
Freezing: Liquid to Solid
When a liquid loses heat, its particles slow down and lose energy. As the temperature drops to the freezing point, the particles arrange themselves into fixed positions, forming a solid.
Boiling: Liquid to Gas
Heating a liquid increases the energy of its particles. At the boiling point, the particles have enough energy to break free from the liquid’s surface and become a gas.
Condensation: Gas to Liquid
When a gas cools, its particles lose energy and move closer together. When the temperature drops to the condensation point, the gas turns into a liquid.
Sublimation: Solid to Gas
Some solids can directly change into gas without becoming a liquid first. This happens when the particles gain enough energy to break free from their solid state and become a gas.
Deposition: Gas to Solid
Deposition is the process where a gas changes directly into a solid without becoming a liquid first. This occurs when gas particles lose enough energy to form a solid structure.
Solids, liquids, and gases differ in their properties:
Solids have a fixed shape and volume. The particles in solids are closely packed together in a regular pattern, which makes them rigid and hard.
Liquids have a definite volume but take the shape of their container. The particles in liquids are close together but can move around, allowing liquids to flow.
Gases have no fixed shape or volume. The particles in gases are far apart and move freely, allowing gases to expand and fill any space.
Property | Solid | Liquid | Gas |
---|---|---|---|
Shape | Fixed | Takes the shape of its container | No fixed shape, fills any container |
Volume | Fixed | Fixed | No fixed volume, expands to fill space |
Particle Arrangement | Closely packed in a regular pattern | Close together but not in a fixed pattern | Far apart and move freely |
Movement of Particles | Vibrate in place, little movement | Move around each other, allowing flow | Move quickly and freely in all directions |
Examples | Rock, ice, wood | Water, milk, oil | Air, helium, steam |
