Study Notes

States of Matter

Matter exists in three states: solid, liquid, and gas, determined by the arrangement and movement of particles.
Solids have a definite shape, distinct boundaries, and fixed volume.
Liquids have a fixed volume but take the shape of their container, flowing easily from one to another.
Gases have neither fixed shape nor volume, expanding to fill their container.

Properties of Solids

Solids maintain their shape regardless of the container.
Hammering or stress can break solids, demonstrating their rigidity.
Examples include a pen, book, and wooden stick, all showcasing fixed volume and shape.

Properties of Liquids

Liquids can flow and take the shape of their containers without changing volume.
Spilling a liquid will cause it to spread out and flow.
Attempts to compress liquids result in little to no alteration in volume due to close particle arrangement.

Particle Theory of Matter

Historical debate: one school viewed matter as continuous, while the other recognized matter as composed of particles.
Experiments, including dissolving potassium permanganate in water, show that even small amounts can color large volumes, indicating multiple tiny particles.

Characteristics of Particles

Matter particles are spaced and continually in motion, allowing movement and interaction among different types of matter.
Diffusion occurs when particles spread from areas of high concentration to low concentration, as seen with odors and colored liquids.

Changes of State

Ice (solid) transforms into water (liquid) by melting, which occurs at a specific temperature without excess heat increasing temperature (latent heat).
Heat energy is required to change solid into liquid; for water, this energy is referred to as latent heat of fusion.
Water (liquid) converts to water vapor (gas) upon boiling.

Sublimation and Deposition

Sublimation refers to the transition from solid to gas without becoming a liquid, while deposition is the reverse process.

Effects of Pressure on States

Distances between particles vary based on the state of matter; applying pressure can compress gases into liquids or solids.
The pressure of gases is measured in atmospheres (atm) or Pascals (Pa); standard atmospheric pressure is 1 atm (101,325 Pa).

Variables Influencing Evaporation

The rate of evaporation depends on several factors: temperature, surface area, and wind velocity.
A variable temperature can affect how long it takes for water to evaporate under different conditions, such as humidity and airflow.
