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.
