Definite volume; no definite shapeHow do you think the particles behave?

Fluid – substance that can flow and take the shape of it’s container

PropertiesPropertiesRelatively 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

PropertiesPropertiesSurface Tension – a force that tends to pull adjacent parts of a liquid’s 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 ?

PropertiesPropertiesCapillary 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 liquid

Where do you see this in lab?

PropertiesPropertiesVaporization –a liquid or solid changes to the gas phase. Ex:perfume

Evaporation–particles escape from the surface of a non boiling liquid and enter the gas state Ex: sweat

Liquid particles have diff. kinetic E’s ; the higher ones can escape liquid surface and enter gas phase

Formation 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.
