Liquids10.2

LiquidsFun Fact - Least common type of matter!Definite volume; no definite shapeHow do you think the particles behave?Fluid substance that can flow and take the shape of its container

PropertiesRelatively high density most substances are more dense as a liquid than a gas slightly less dense in liquid state than as in a solid Relative incompressible Ability to diffuse slower than in gases, but the higher the temp, the faster the diffusion

PropertiesSurface Tension a force that tends to pull adjacent parts of a liquids surface together, thus decreasing the surface area to the smallest possible size.The ___________ the attractive force, the higher the surface tension. Water surface tension is or ?

PropertiesCapillary action the attraction of the surface of a liquid to the surface of a solid. Water in a tube continues to rise until attractive forces of particles to the wall are balanced by weight of liquidWhere do you see this in lab?

PropertiesVaporization a liquid or solid changes to the gas phase. Ex:perfumeEvaporationparticles escape from the surface of a non boiling liquid and enter the gas state Ex: sweatLiquid particles have diff. kinetic Es ; the higher ones can escape liquid surface and enter gas phase

PropertiesFormation of Solids How does a liquid form a solid?It Freezes the physical change of a liquid to a solid by removal of energy as heat is called freezing or solidification.

Particles in constant motion, attractive forces are more of a factor than in gases since they are closer, move past each other *
