-How do you find the volume of a liquid? A cube? An irregular solid? liquid- measure it cube- length times width times hight irregular solid- water
displacement or a graduated clyinder.
-Solve: If each side of a cube is 8cm, what is the volume? (show equation and work) V= LxWxH
V= 8x8x8
V=512 cm cubed
-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=LxWxH
V= 7x3x2
V= 42 cm cubed
-Mass.- the amount of matteer in an object
-Volume- the amount of space a object takes up
-Density- how much mass per space
-Water displacement- you would use it to find the mass of a irregular object
-Weight and Mass difference- different deffinitions
-What tool do you use to find the mass of an object? triple beam balance, spring scale, doulbe pan balance
-Drop- one bead of water
-Heap- one drop of liquid
-Know why soapy water has less cohesion than water- Because soap breaks cohesion
-Surface Tension- skin of a liquid
-Viscosity- resistance to flow
-Profile of an object- a picture from the side of an object

-Sublimation- when a solid turns into a gas or a gas turns into a solid. Heat loss and heat gain. Example- dry ice
-Condensation- when a gas turns into a liquid. Example- foggy mirror. heat loss
-Freezing- when a liquid turns to a solid. Heat loss example making ice
-Melting- when a solid turns into a liquid example ice melting heat gain
-Evaporating- when a liquid turns into a gas example water boiling heat gain
-Cohesion-attraction between like molecules
-Adhesion- attraction between unlike molecules
-Five Examples of cohesion- soap soap, water water, cooking oil cooking oil, milk milk, glycrol glycrol/
-Five Examples of adhesion- milk water, soap milk, cooking oil milk, soap gycerol, alchol water.
