What are the three states of matter?

The three states of matter are solid, liquid, and gas.

What is the defining characteristic of a solid?

A solid is characterized by having a definite shape and volume with particles closely packed together in a fixed arrangement.

How does a liquid differ from a solid?

A liquid differs from a solid in that it has a fixed volume but takes the shape of its container, whereas a solid has a fixed shape and volume. Liquids flow and have particles that are free to move past one another, while solids have particles that are tightly packed in a specific arrangement.

What is the shape and volume of a gas?

A gas does not have a definite shape or volume as it takes the shape and volume of the container it is in. Gas particles are constantly moving and spaced far apart, giving them the ability to expand to fill any space available to them.

How do particles in a solid arrangement compare to those in a liquid or gas?

Particles in a solid arrangement are tightly packed together in a fixed position and vibrate in place, while particles in a liquid have more space between them and can move past each other, flowing and taking the shape of their container. In a gas, particles are much further apart and move freely with high speed, colliding with each other and the walls of their container. So, the main difference lies in the spacing and movement of particles in solids, liquids, and gases.

Explain what happens during the process of melting.

During melting, a solid substance is heated to a temperature at which its particles gain enough energy to overcome the forces holding them in a fixed position. As a result, the particles start to vibrate more vigorously and break free from their fixed positions, transitioning from a solid state to a liquid state. This process involves the absorption of heat energy, causing the substance to change from a solid to a liquid form without a change in temperature, as the absorbed energy is used to weaken the intermolecular forces holding the solid structure together.

Describe the process of condensation.

Condensation is the process in which a gas or vapor transforms into a liquid. This occurs when the molecules within the gas lose energy and slow down, allowing them to come together to form liquid droplets. Condensation typically happens when the temperature of the gas drops below its saturation point, causing the molecules to lose enough energy to transition into a liquid state. This process is commonly observed when warm air cools down and condenses into water droplets, such as when steam turns into water on a cold surface.

How does a gas change into a liquid?

A gas changes into a liquid through a process called condensation. This occurs when the gas loses energy, typically through cooling, causing the molecules to slow down and come closer together, forming a liquid state. This change in state is known as a phase transition, where the gas molecules transition from a more random and spread-out motion to a more orderly and condensed arrangement in the liquid state.

What is the process of evaporation?

Evaporation is the process by which a liquid turns into a gas when heat is applied. When the temperature of a liquid rises, the molecules within the liquid gain energy and move more quickly. This increased movement causes some of the molecules to break free from the surface of the liquid and escape into the air as vapor. Evaporation continues until the liquid has entirely evaporated or reached equilibrium with the surrounding air.

How does sublimation differ from melting and vaporization?

Sublimation is the process where a solid substance transitions directly into a gas without passing through the liquid phase, like when dry ice turns into carbon dioxide gas. Melting, on the other hand, is the transition of a solid substance into a liquid, such as ice turning into water. Vaporization is the process in which a liquid turns into a gas, like when water boils and turns into steam. So, while sublimation skips the liquid phase entirely, melting and vaporization involve the transition between solid and liquid, and liquid and gas, respectively.
