Atoms and Their Structure
This is the neutral subatomic particle of an atom.
What is a Neutron?
The ability of a substance to dissolve in another substance.
What is Solubility?
This is the tool you use to measure the melting point.
What is a Thermometer?
Balance, Scale and Digital Scale are used to measure this.
What is Mass?
The ability of an object to float on another object.
What is Density?
This is the positive subatomic particle of an atom.
What is a Proton?
Ice Melting and returning back to Ice.
What is a Physical Change?
Temperature at which a substance turns into a liquid.
What is Melting/Melting Point?
Beaker, Graduated Cylinder, and a Measuring Cup are used to measure this.
What is Volume?
If an item floats on top of water.
Why is the Density less than 1?
Gold, Hydrogen, and Oxygen are all examples of this.
What is an Element?
The Foil rusting in the Copper chloride (Blue Chemical)
What is a Chemical Change/Reaction?
When a solid is melting into a liquid, the particles do this.
What is Spread Apart?
You have an empty air tank and a full air tank and compare them using a scale.
How do you figure out the mass of air?
Density=Grams/Centimeters3
What is the formula of Density?
This is the Negative subatomic particle of an atom.
What is an Electron?
Boiling Crawfish and steam is coming out the pot.
What is a Physical Change?
100 degrees Celsius (212 degrees Fahrenheit)
What is the Melting Point of Water?
It takes up space and has weight.
What is Matter?
A piece of wood that has a mass of 25.0 grams and a volume of 29.4 cm3, what is the density?
What is 0.85 g/cm3
The Periodic Table is structured using this.
What is an Atomic Number?
Mixing eggs, flour and butter to make brownies.
What is a Chemical Change?
One object melts at 100 degrees and another object melts at 3000 degrees.
Why do things melt at different temperatures? or Why are they made of different elements?
Gold brick and a Gold ring are the same substance but weigh differently.
Why we do not use Mass as a property?
I threw a plastic ball in the pool for my dog to fetch. The mass of the ball was 125 grams. What must the volume be to have a density of 0.500 g/mL. ( I want it to float of course!)
What is 250 cm3
