Density
Density times Volume. D x V
What is the formula for Mass?
It indicates the total number of protons in an element.
What is the atomic number?
This is Solubility.
What is the ability of a substance to dissolve?
It contains only one type of atom.
What is an element?
This variable is located on the "X" axis.
What is the manipulated variable?
Mass Divided by Density. M/D
What is the formula for volume?
The total number of protons and neutrons.
What is the atomic mass?
A reaction which leads to a new substance with different properties.
What is a chemical change?
Protons, Neutrons, and Electrons.
What are the three components of an atom?
This variable is located on the "Y" axis.
What is the responding variable?
Grams per cubic centimeter. g/cm3
What are the units of measure for density?
Elements located in the far right hand column of the periodic table.
What are the noble gases?
This is an example of a phase change.
What happens when a substance changes from a solid to a liquid?
or
What happens when a substance changes from a liquid to a gas?
Protons and neutrons?
What are found in the nucleus of an atom?
or
What makes up the mass of an atom.
The atoms or molecules start to move faster and grow further apart.
What happens to atoms and molecules of a substance as heat is added?
You can find this by using displacement.
How do you find the volume of an irregular object?
Mostly metals.
What type of elements make up the majority of elements in the periodic table?
The graph line indicated little change in temperature during these two times when heating fresh and salt water.
What happened to the graph line when the water was melting and boiling?
Contains more than one atom bonded together.
What is a molecule?
It states that the mass of the product should be the same as the mass of the reactant.
or
It means that matter can neither be created nor destroyed.
What happens to the total amount of mass in substances before and after a reaction?
or
What is the Conservation of Energy?
By placing the three liquids in a density tower.
How do you find out which of three liquids is more dense?
I have only one proton and no neutrons.
What is Hydrogen?
This is when a substance turns directly from solid to a gas.
What is sublimation?
This is what it's called when there are a different number of protons than electrons in an atom.
What is an ion?
THE DAILY DOUBLE (DOUBLE THE VALUE)
The air in the hot air balloon becomes less dense so the balloon rises.
What happens to the density of the air in a balloon when heated?
