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
the first ingredient in a store bought bath bomb
baking soda
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
The property at which a substance changes from a solid to a liquid
Melting point
Provide three pieces of evidence that prove gas was produced in the soda bottle.
the mass went down after we opened the soda bottle
the soda bottle got cold
the soda bottle bubbled and fizzed when it was opened
Melting point of ice in Celsius
0 degrees Celsius
All matter takes up ______ and has _______
Space, mass
Which state of matter is the most dense?
Solid
What property is defined as how tightly packed a substance is?
Density
name 6 substances that are common in store bought bath bombs
baking soda, salt, sugar, epsom salt, corn starch, oil, citric acid, corn starch, water
How do we know if substance is soluble in water?
The substance dissolves completely.
________ 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
The solvent in a saltwater solution
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.
The 3 substances that did not dissolve in water
cornstarch
olive oil
coconut oil
In a closed system, matter cannot exit so what stays the same?
Mass
Which state of matter has the slowest moving particles?
The solute in Oobleck
cornstarch
the reason why the bag did not expand when we crushed the bath bombs
the gas is not trapped inside the bath bomb
the measure of how "thick" or "resistant to flow" a liquid is
viscosity
Give an example of an open system and name the property that can change
open balloon, mass
