Explanation
Liquids can be converted into solids by cooling , a process known as freezing or solidification. As the temperature decreases, the particles of the liquid slow down and come together, forming a solid.

Explanation
Gases can be converted into liquids by cooling , a process known as condensation . As the temperature decreases, the particles of the gas slow down and come together, forming a liquid.

Explanation
Liquids can be converted into gases by heating , a process known as vaporization or evaporation. As the temperature increases , the particles of the liquid gain energy and move faster, eventually breaking free from the surface tension of the liquid and turning into a gas.

Explanation
Solids can be converted into liquids by heating, a process known as melting. This occurs when the particles of the solid gain enough energy to break free from their fixed positions and start moving freely, resulting in a liquid state.

Explanation
Matter can change from one form to another through various processes, including: Heating : Melting ( solid to liquid ), Vaporization ( liquid to gas ) Cooling : Freezing ( liquid to solid ), Condensation ( gas to liquid ) For example , ice (solid) can change to water (liquid) by heating, and water (liquid) can change to steam (gas) by further heating. Similarly, steam (gas) can change to water (liquid) by cooling, and water (liquid) can change to ice (solid) by further cooling.

Explanation
A solution is a type of mixture that is homogeneous , meaning it has a uniform composition and properties throughout. It is a mixture of two or more substances, where one substance (the solute) is dissolved in another substance (the solvent).

Explanation
Liquids take the shape of a container because they have a fixed volume but no fixed shape . They conform to the shape of the container they are placed in.

Liquids take the shape of a container because they have a fixed volume but no fixed shape . They conform to the shape of the container they are placed in.

Explanation
Solids, liquids, and gases can mix together to form a mixture. Which is a physical combination of two or more substances in which each substance retains its chemical properties.

Explanation
Gases are the state of matter that takes both the shape and volume of a container they are placed in. They expand to fill the container and conform to its shape. Liquids , take the shape of a container but maintain their own volume. Solids maintain both their shape and volume , regardless of the container they are placed in.

Explanation
A gas is a state of matter that has neither a fixed shape nor a fixed volume. It expands to fill its container and takes the shape of its container. Gases are highly compressible and can change shape and volume easily. Liquid : A liquid has a fixed volume but not a fixed shape. Solid : A solid has both a fixed shape and a fixed volume.
