Elements
I have a single proton in my nucleus.
What is hydrogen?
This phase has an interlocking lattice structure.
What is solid?
What type of "changes" are there in chemistry? Name at least three.
What are phase changes, physical changes, chemical changes, temperature changes, pressure changes, volume changes?
What is force?
Force = mass x acceleration
If you tap in for this, you will have to walk to the board and draw me BOTH a CO2 molecule and a water molecule.
Checked on board. :)
In my diatomic state, I am a necessary ingredient in human life.
What is oxygen?
This phase is able to flow around, but it is still interconnected atoms (just not in lattice structure).
What is liquid?
What change is happening when the melted wax of a burning candles solidifies after the candle is blown out?
What is freezing?
The applied force required to hold something stable off the ground is normally referred to as WHAT force?
What is the NORMAL force?
What is the acceleration due to gravity on any object on which there are no other forces acting?
What is 9.81 m/s2?
This is the atomic symbol for silver.
What is Ag?
This phase has no structure and is comprised of atoms just free-bouncing around and off each other.
What is gas?
What are two signs of a chemical change?
What is odor change, color change, formation of a precipitate, gas production, the release of light, or temperature change?
Does an inclined plane INCREASE or DECREASE the force of gravity pulling on an object?
What is DECREASE?
What are the six simple machines?
What are inclined plane, lever, wedge, wheel and axle, pulleys, and screw?
What element has the most protons in its nucleus?
This is what it is called when elements or molecules shift from one phase to another phase.
What is a phase change?
In the chemical reaction between baking soda (bicarbonate) and vinegar, what are the liquid and gaseous products?
Liquid: H2O
Gas: CO2
What unit measures FORCE?
What is the Newton?
What are Newton's Three Laws of Motion?
What is 1- an object at rest stays at rest or an object in motion stays in motion unless acted upon by an outside force. 2- force = mass x acceleration and 3- for every action there is an equal and opposite reaction?
This element is required to be present in order for something to be considered organic.
What is Carbon?
This phase occurs when elements or molecules become so hot that they lose their electrons and become charged particles.
What is plasma?
There are six types of phase changes. Condensation is when a gas becomes a liquid. Boiling is when a liquid becomes a gas. Freezing is when liquid becomes solid. Melting is when solid becomes liquid. There are two more. ONE when gas becomes solid. A SECOND when a solid becomes a gas. What is the name of these two types of phase changes?
What are deposition (gas to solid) and sublimation (solid to gas)?
When you are free falling in that glider with only air pressure to hold you up, what is CAUSING the air to hold you up?
What is the push of your glider against the individual air particles!
What are VECTOR and SCALAR measurements AND give an example of each kind.
Vector--measurements with direction
Scalar--measurements with no direction
