States of Matter
Which state of matter is the least dense?
Gas
What property is tested by seeing if the substance dissolves in a liquid?
Solubility
Which gases are potential candidates for the identity of the bath bomb gas?
Argon, nitrogen, carbon dioxide
To form a scientific argument, you need what 3 components?
A claim, evidence, and big ideas (key concepts)
All matter is made of _______
Particles
Which state of matter has a medium density in comparison with the other two?
Liquid
What property is tested by lighting the substance on fire?
Flammability
What 3 substances are required in bath bombs to generate a gas?
Citric acid, baking soda, and water
Let's say you have the question: "What possible gases could the bath bomb gas be?"
What would be a reasonable claim statement?
The bath bomb gas could be carbon dioxide, nitrogen, or argon
All matter takes up ______ and has mass
Space
Which state of matter is the most dense?
Solid
What property is defined as how tightly packed a substance is?
Density
Density tests (BB gas is denser than air) + flammability tests (BB gas isn't flammable) let us eliminate all other gases except those 3.
________ of substances can help us identify what they are/differentiate between substances
Properties
Which state of matter has particles that are moving faster than the other states?
Gas
An unknown solid dissolves in water. How does that help you figure out what substance it is?
Solubility is a property, so we can eliminate any substances that don't dissolve in water
When we tested an open system by putting bath bombs in water in a bottle, why did the mass decrease?
Gas is produced as part of the bath bomb mixing in water. In an open system, matter can escape, and since gas has mass, the overall mass decreased.
What is this argument missing?
The bath bomb gas could be argon, carbon dioxide, or nitrogen. Denser gases sink in less dense gases, so that's how we know.
In a closed system, matter cannot exit so what stays the same?
Mass
Which state of matter has the slowest moving particles?
An unknown gas is flammable. How could that help you determine what it is?
Because flammability is a property, so you could eliminate any nonflammable gases
How does the property, state of matter, help us to know that the gas produced by bath bombs is NOT originally in the bath bombs?
State of matter is a property. Since none of the starting ingredients in a BB are gases, that means the gas didn't originally exist in the bath bombs as a gas.
What is this argument missing?
The bath bomb gas could be argon, carbon dioxide, or nitrogen. When we investigated density, we found the BB gas is more dense than air. These 3 gases are also more dense than air.
Tying in a big idea to support the evidence
Denser gases ____ when placed in less dense gases
Sink
