Principles of Chemistry - States of Matter

These flashcards cover key concepts related to the states of matter, interconversions, properties of solutions, and diffusion, summarizing important definitions and principles for a foundational understanding of chemistry.

What are the three states of matter?

Solid, liquid, and gas.

How are gas particles arranged compared to solid and liquid particles?

Gas particles are the most spread apart with a random arrangement.

What occurs during melting?

A solid turns into a liquid.

What is the term for a liquid turning into a gas?

Boiling.

What is diffusion?

Movement of particles from an area of high concentration to an area of low concentration.

Can diffusion occur in solids? Why or why not?

No, because particles in solids cannot move from place to place.

Define solvent in a solution.

The liquid in which a solute dissolves.

What do we call a solution in which no more solute can be dissolved?

Saturated solution.

What is solubility measured in?

Grams of solute that will dissolve in 100 g of solvent.

How does temperature affect the solubility of solids?

The solubility of solids generally increases as temperature increases.
