Anything that has mass and takes up space.
Matter
A solid has __________ particles that _______ and so they can't move past each other.
tightly packed & vibrate
Explain how the particles are in a liquid.
They are less tightly packed than solids, they can move past each other and bump each other.
Gas particles have _____________ shape & ____________volume.
NO definite shape or volume, fills its container
Mass is measure using this tool...
Triple Beam Balance
When water changes to gas this is known as
**DOUBLE JEOPARDY**
vaporization
What is an example of surface tension?
Water strider or paper clip floating on top of a liquid
How do you calculate density of a solid, regular shaped object?
**DOUBLE JEOPARDY**
get mass using TBB
get volume; lxwxh in cm3
divide mass/volume
Density= Mass/Volume
when gas turns to a liquid
condensation
Volume is measured using this formula;
LxWxH or Liquid Displacement Method
Honey is less viscous than pancake syrup.
FALSE
Some examples of gas are;
What substance weakens bond in surface tension?
Soap or Soapy water
Milk is more viscous than water.
True
The amount of mass in a fixed volume
Density
A property of a liquid, it is the liquids resistance to flowing.
Water molecules are attracted and bond with other water molecules.
Define adhesion.
Water molecules can attach with different types of molecules.
Ice tea (less visc) and liquid sugar (more visc)
lemon juice (less) and strawberry syrup (more)
Solid goes directly to a gas,
sublimation, like snow sometimes converts directly to a gas
What is an amorphous solid and name one example.
Amorphous solid is a solid in which particles are NOT arranged in a repeating, organized pattern known as a "lattice".
Butter, cotton candy, glass, rubber, many plastics
Describe the lab we completed on viscosity. What did you learn?
We tested the time liquid took to flow to another cup, 2 trials, average and we saw which liquids have a resistance to flowing as compared to other liquids.
What is a crystalline solid and name one example.
A crystalline solid is a solid with a regular, repeating pattern, organized patter. Examples are; table salt, diamonds, gold, silver
Describe the lab we completed with the dropper, water and pennies, what did you learn from this lab?
Dropped water on penny until the "surface tension" broke, we are able to see the attractive nature of water molecules.
What is surface tension?
An inward pull among the molecules of a liquid that brings the molecules on the surface together
