Chapter 11 section 1Solid: Fixed shape. Fixed volume. Typically forms crystals.Liquid: No fixed shape. Fixed volume. Viscosity-describes a liquids ability to flow. High viscosity = a thick liquid that flows slowly. Low viscosity = a thin liquid that flows quickly. Surface Tension-the tendency of liquids to decrease surface area to the smallest size possible. Cohesion-Liquid particles attraction for each other. Adhesion-Liquids attraction for particles of a solid surface. Capillary Action-The process of moving a liquid due to the cohesion of liquid molecules.Gas: No fixed shape. No fixed volume. A gas will expand until it is evenly distributed throughout its container.Changes of State: Matter can move between the three states. When describing this movement it is necessary to consider energy and temperature.
Outside Arrows (green) = A loss of energy decreasestemperature and slows particle movement.Inside Arrows (blue) = An increase of energy increasestemperature and speeds up particle movement.
Get the point?Boiling Point: Temperature and pressure where liquid and gasare at equilibrium. Liquid to gas.Melting Point: Temperature and pressure where a solid liquid.Freezing Point: Temperature and pressure where a liquidsolid.The melting point and freezing point of water is the sametemperature. If the water is solid it will melt at 0oC. If the water is liquid it will freeze at 0oC.
