Particle Theory and Types of Substances Quiz

Study Notes

Everything around us is made up of particles, even we ourselves
Particles can form pure substances, where all particles are identical, or mixtures, where different types of particles are present
Pure substances can be thought of as exclusive parties with only one type of particle, while mixtures are open parties with various types of particles
Particle theory helps distinguish between pure substances and mixtures, as in pure substances, particles are identical, while in mixtures, they retain their individual properties
Homogeneous mixtures are uniformly distributed throughout the mixture, like a well-blended smoothie, where the components cannot be distinguished
Heterogeneous mixtures, like a bowl of trail mix, have components that are not uniformly distributed and can be easily separated
Solubility is the ability of a substance to dissolve in a solvent; water is a universal solvent due to its polarity
Saturated solution is a party that's at full capacity, while an unsaturated solution can still accommodate more guests (solute)
Concentration is a measure of the amount of solute present in a solvent
Separation methods include sedimentation, decantation, filtration, evaporation, distillation, and centrifugation
Elements are pure substances made up of a single type of atom, while compounds are pure substances made up of multiple types of atoms bonded together
Elements and compounds have unique properties and can be interchangeable
Particle theory helps explain the behavior of matter around us.
