-Sublimation- soild to gas
-Condensation- gas to liquid
-Freezing- liquid to soild
-Melting- soild to liquid
-Evaporating- liquid to gas
-Cohesion- attractive force between two like moecules
-Adhesion- attractive force between two unlike molecules
-Five Examples of cohesion- water to water, glycerol to glycerol, alcohol to alcohol, soapy water to soapy water, cooking oil to cooking oil
-Five Examples of adhesion- water to alcohol, water to glycerol, soapy water to alcohol, cooking oil to water, alcohol to cooking oil
-How do you find the volume of a liquid? A cube? An irregular solid?
measur it, length x width x height, water displacement
-Solve: If each side of a cube is 8cm, what is the volume? (show equation and work)
V= l x w x h
V= 8 x 8 x 8
V= 512cm3
-Solve: If the length of a cube is 7cm, the width is 3cm, and the height is 2cm, what is the volume? (show equation and work)
V= l x w x h
V= 7 x 3 x 2
V= 42cm3
-Mass- the amount of matter in an object
-Volume- the amount of space an object takes up
-Density- the amount of mass in a given area
-Water displacement- the way to measure an irregular soild
-Weight and Mass difference- weight is effected by gravity, and mass always stays the same
-What tool do you use to find the mass of an object?- triple beam balance
-Drop- one bead of liquid
-Heap- more than one bead of liquid
-Know why soapy water has less cohesion than water- the soap in the water breaks the surface tension
-Surface Tension- the skin of a liquid
-Viscosity- the resistance of a liquid flowing
-Profile of an object- side view of an object
-Condensation- gas to liquid
-Freezing- liquid to soild
-Melting- soild to liquid
-Evaporating- liquid to gas
