GRADE 8 Science – Properties of matter in the different states Quiz

Solids have a definite shape and volume because the particles are closely packed together and have strong forces of attraction holding them in place.

Liquids have a definite volume because the particles are close together, but they can flow and take the shape of the container they are in.

Gases do not have a definite shape or volume because the particles are far apart and move freely, filling the entire space available to them.

Plasma is the fourth state of matter where the particles are ionized and have no fixed shape or volume. It is formed at extremely high temperatures.

Solids have the least energy among the states of matter, and the particles are arranged in a fixed, orderly structure due to strong forces of attraction.

Liquids have more energy than solids, allowing the particles to flow and move past each other, but less than gases, so they have a definite volume.

Gases have the most energy among the states of matter, allowing the particles to move freely and have no definite shape or volume.

Gases are commonly found in the Earth's atmosphere and are invisible because the particles are spread far apart and move freely.

Liquids are most commonly found in our everyday life, including materials like water, milk, and juice, as they can flow and take the shape of their container.

Plasma is the rarest state of matter on Earth but is often found in stars and lightning due to its charged ionized particles at high temperatures.

In a liquid, the particles are close together like in a solid, but they can still move around each other, allowing the liquid to take the shape of its container while maintaining a definite volume.

In a solid, the particles are closely packed together and vibrate in place, giving the solid a definite shape and volume.

In a gas, the particles are far apart and move freely, filling the entire space of their container. This lack of definite shape and volume allows gases to expand to fill any container.

Plasma is the fourth state of matter, formed at very high temperatures when atoms become ionized. It is composed of positively charged ions and free electrons, giving it unique properties not found in solids, liquids, or gases.

Liquids take the shape of their container but have a definite volume, distinguishing them from gases which do not have a definite shape or volume.

Plasma has the highest energy and the most freedom of movement of its particles, as they are ionized and not bound together in fixed positions like in solids, liquids, or gases.

Solids have the least energy and the least freedom of movement of their particles, as they are tightly packed together and vibrate in fixed positions, unlike the more free-moving particles in liquids, gases, or plasma.

Gases can be compressed into a smaller volume with the application of pressure, unlike liquids and solids which are much less compressible due to the close packing of their particles.

Solids have the strongest intermolecular forces holding their particles together, which is why they have a definite shape and volume compared to the weaker forces in liquids and gases.

Gases have the weakest intermolecular forces between their particles, allowing them to move freely and fill the space of their container, unlike the stronger forces in solids and liquids.

Solids have the highest density and the least compressibility, as their particles are tightly packed together and have strong intermolecular forces that prevent much compression compared to liquids and gases.

Gases have the lowest density and the most compressibility, as their particles are far apart and have weak intermolecular forces, allowing for significant compression compared to liquids and solids.

Liquids have the ability to flow and take the shape of their container, distinguishing them from solids which have a fixed shape and gases which expand to fill the container.

Plasma has the ability to conduct electricity due to the presence of free electrons and positively charged ions that can move freely, unlike the other states of matter where electrons are bound within atoms or molecules.

Solids have the ability to maintain their shape and volume regardless of their container, making them distinct from liquids and gases that take the shape of their container.

Gases can change both their shape and volume to fit their container, unlike solids which maintain their shape and volume or liquids which take the shape of their container but maintain a definite volume.

In a solid, the particles are closest together and have the least energy, as they are tightly packed and vibrate in fixed positions, while the particles in liquids, gases, and plasma have more energy and are further apart.

Gases change their volume the most with changes in temperature and pressure, as they are highly compressible and their particles can move freely, whereas solids and liquids have less volume change due to their closer-packed particles and stronger intermolecular forces.

Solids have the ability to be shaped or molded into different forms due to their fixed shape and volume, unlike liquids and gases which take the shape of their container.

Liquids have the ability to evaporate and change into a gas when heated, as the particles gain enough energy to break free from the liquid phase and enter the gaseous phase, unlike solids that undergo sublimation or gases that undergo ionization to become plasma.

Gases have the ability to condense and change into a liquid when cooled, as the particles lose energy and come closer together to form a liquid, unlike solids that undergo deposition or liquids that undergo freezing to become solid.

Liquids have the property of surface tension due to the attraction between their particles, creating a strong cohesive force at the surface that allows liquids to form droplets or maintain a flat surface.

Solids have the property of elasticity and can return to their original shape after deformation, as the particles are held together by strong forces that pull them back into place, unlike liquids and gases which flow and do not retain their shape.

Gases have the property of diffusion and can mix with other substances easily due to the random motion of their particles, allowing them to spread out and form a homogeneous mixture, unlike solids and liquids which diffuse at a much slower rate.

Solids can undergo sublimation and change directly from a solid to a gas without passing through the liquid phase, as is the case with dry ice (solid carbon dioxide) turning into carbon dioxide gas under certain conditions.
