What is the definition of a solid?

A solid is a form of matter that has a definitive shape and volume, with particles that are closely packed together in a fixed arrangement. Solids maintain their shape and do not easily flow, making them distinguishable from liquids and gases.

How do particles in a solid move?

Particles in a solid vibrate in fixed positions due to their strong intermolecular forces, which keep them in a rigid and relatively ordered arrangement. These vibrations are very small and occur around equilibrium positions, meaning that while the particles do not move freely around each other, they still have a small amount of kinetic energy causing them to vibrate in place.

What are some examples of solids in everyday life?

Some examples of solids in everyday life include a table, a book, a cell phone, a brick, a desk, a piece of wood, a spoon, a shoe, a computer, and a rock.

Define a liquid.

A liquid is a state of matter that has a definite volume but no definite shape, meaning it can flow and take the shape of its container. Liquids have particles that are close together and are able to move past each other, allowing them to flow easily.

How do particles in a liquid move?

Particles in a liquid move by constantly vibrating and rotating in random directions due to the molecules having more energy than in a solid state, allowing them to flow and take the shape of the container they are in. This movement is what gives liquids their ability to pour and be easily manipulated, as the particles are free to move and slide past each other.

Give examples of liquids commonly found around the house.

Water, milk, juice, cooking oil, vinegar, cleaning agents like bleach and disinfectants, hand soap, shampoo, and laundry detergent are some examples of liquids commonly found around the house.

What is a gas?

A gas is a state of matter in which the substance has no definite shape or volume, and its particles are widely spaced and move freely at high speeds. Gases can expand to fill any container they are placed in and are highly compressible.

How do particles in a gas move?

Particles in a gas move in random and continuous motion due to their high kinetic energy. They collide with one another and with the walls of their container, causing changes in direction and speed. This constant movement is what gives gases their ability to fill any container they are placed in, as the particles are free to move and spread out to fill the available space.

Provide examples of gases in nature or industry.

Examples of gases in nature include oxygen in the air, carbon dioxide released by plants during photosynthesis, and methane produced by livestock. In industry, common gases include nitrogen used in food packaging to extend shelf life, hydrogen in fuel cells for clean energy production, and chlorine for water purification.

How can substances change from one state to another (solid to liquid, liquid to gas, etc.)?

Substances change from one state to another through processes such as melting, freezing, boiling, condensation, sublimation, and deposition. These changes are caused by alterations in temperature and pressure, which affect the arrangement and movement of particles within the substance. For example, when a solid is heated, its particles gain energy and begin to move more freely, causing the substance to melt and become a liquid. Likewise, when a liquid is heated further, its particles gain even more energy and move faster, eventually causing the liquid to vaporize and turn into a gas.
