Being Dense Is Hard
Feeling Tense?
100
The "sticking" force that holds one material to a different material.
What is adhesion?
100
The force that causes similar molecules to be attracted to each other holding them together.
What is cohesion?
100
Movement of water due to an object being placed in the water.
What is displacement?
100
How much of a substance is in a unit of space.
What is density?
100
Occurs when surface molecules in a liquid are held together by strong cohesive forces. The "skin" on the surface of the liquid resists being broken.
What is surface tension?
200
The most adhesive liquid that we compared.
What is corn oil?
200
The most cohesive liquid we compared.
What is water?
200
An example of positive buoyancy.
Answers will vary.
200
The one that is denser between water and a pin.
What is a pin?
200
The video we saw that had to do with surface tension.
What is the "bouncing" drop of water?
300
The least adhesive liquid that we compared.
What is water?
300
The least cohesive liquid we compared.
What is soapy water?
300
Why a steel ship can float even though steel is more dense than water.
What is the water it displaces weighs more than the ship?
300
The denser of hot or cold, and salt or fresh water.
What is cold salt water.
300
Two investigations that demonstrated water's property of surface tension.
What is two of the following: * Pin Float * Fold and Float * Strong Water
400
The name of an investigation where we looked at the adhesive properties of four liquids.
What is "Sliding Drops Lab?"
400
The name of an investigation where we looked at the cohesive properties of four liquids.
What is "Drops Lab?"
400
The denser of wood or eggs.
What are eggs?
400
Why the foil will eventually break the surface tension if you keep folding it.
What is the weight is concentrated on a smaller and smaller area of water.
500
The definition of adhesion.
What is "the "sticking" force that holds one material to a different material.
500
The definition of cohesion.
What is "the force that causes similar molecules to be attracted to each other holding them together?
500
Why a greater volume of water is displaced when an anchor is placed anchor placed in salt/fresh water.
What is a greater amount of water is displaced when an anchor is placed in fresh water because fresh water weighs less for the same volume.
500
The formula for finding density.
What is: Density = Mass / Volume
500
Why a wet pin can't sit on "surface" of the water.
What is the cohesive force of the water will sink a wet pin?
