Chemistry bond energy, solutions, terms - phase change key terms

Flashcards based on notes covering solids, liquids, phase changes, and solutions.

Amorphous

Lacking a definite shape.

Crystalline

Having a crystal structure.

Volatile

Easily reacts.

Vapor Pressure

Pressure of evaporating water.

Viscosity

Thickness of a liquid.

Surface Tension

The attraction of a liquid's surface molecules.

Sublimation

Solids becoming gases.

Boiling Point

Point at which liquid becomes a gas.

Melting Point

The point where a solid becomes a liquid.

Evaporation

When a liquid turns to gas.

Deposition

Gases turning into solids.

Condensation

When a gas turns into a liquid.

Solution

A liquid mixture composed of a solute and a solvent.

Solute

The substance being dissolved into a solvent.

Solvent

A substance that dissolves a solute (e.g., water).

Solubility

The ability to dissolve; like dissolves like.

Saturated

The maximum amount of solute that will dissolve in a solvent.

Unsaturated

Anything less than the maximum amount of solute that can dissolve.

Supersaturated

More solute than can normally be dissolved.

Miscible

Two liquids that can mix. (e.g., lemonade and sweet tea)

Immiscible

Two liquids that cannot mix (e.g., oil and water).

Electrolyte Solution

A solution with ions that conducts electricity.

Nonelectrolyte Solution

A solution without ions that does not conduct electricity.

Dissociation

Solute separates into particles (endothermic).

Hydration

Solvent molecules surround solute particles.

Colligative Property

Solution properties that change when solutes are added.

Colloid

A solution that doesn't stay in solution over time (e.g., milk, paint).

Suspension

A mixture that settles immediately and quickly becomes unmixed.

Alloy

A combination of different metals (e.g., brass, bronze, pewter).
