Vocab Vault
A material made of only one type of particle throughout.
What is a substance?
In this type of system, no matter can get in or out, so mass stays the same.
What is a closed system?
When tested alone in water, this single bath bomb ingredient produces gas bubbles.
What is none of them?
The appearance of these in a liquid is clear evidence that a new gas substance has been created.
What are gas bubbles?
This property explains why helium floats upward when surrounded by air.
What is density?
All solids, liquids, and gases are made of matter, which has mass and takes up this.
What is space?
An observable or measurable characteristic that we can use to identify a substance.
What is a property?
In this type of system, matter can get in or out, so mass can change.
What is an open system?
These three specific substances are required to produce the gas bubbles seen in a bath bomb.
What are citric acid, baking soda, and water?
In lesson 4, this drink mix fizzed the most when combined with baking soda and water.
What is sugar-free lemonade mix?
Properties like density, flammability, and solubility remain constant regardless of this.
What is size?
This is the standard scientific unit used to measure mass on a digital scale.
What is a gram (g)?
Describes a material, like baking soda, that can completely break down and mix into a liquid.
What is soluble?
If a bath bomb fizzes inside a tightly capped plastic bottle, the scale reading will do this.
What is stay exactly the same?
Testing combinations of bath bomb substances showed that the gas comes from this type of event.
What is a chemical reaction?
When a chemical reaction occurs, starting particles interact to form new substances with different ones of these.
What are properties?
If Gas X puts out a flame while Gas Y explodes with a pop, we know they are this.
What are different substances?
Science classrooms use this tool to measure the volume of a liquid.
What is a graduated cylinder?
Bath bomb powder is considered this because it contains several different substances.
What is a mixture?
When a bath bomb is dropped into water in an open beaker, the scale reading does this as gas escapes.
What is decrease (or go down)?
When a lit match is placed in a container filled with bath bomb gas and the flame immediately goes out, it proves the gas has this property.
What is non-flammable?
Testing individual ingredients proved that this powdery ingredient in bath bombs is insoluble and does NOT produce gas[cite: 2, 6].
What is cornstarch?
Denser gases and liquids will do this when surrounded by less dense gases and liquids.
What is sink downward?
Milliliters (mL) and cubic centimeters (cm3) are standard units used to measure this.
What is volume?
Olive oil floating to the top of a beaker instead of dissolving shows it has this property.
What is insoluble?
When gas escapes from an open beaker during a reaction, the scale reading drops because the escaping gas takes this with it.
What is its mass?
Lemonade mix creates gas bubbles when added to baking soda and water because it contains this key ingredient.
What is citric acid?
In a closed container, total mass does not change during a reaction because this cannot get in or out.
What is matter (or particles)?
Placing a lit match into a container of unknown gas will make the flame ignite or burn brighter if the gas is oxygen, but will do this if the gas is carbon dioxide.
What is extinguish the flame (or put the flame out)?
Regular Coke has a higher density than Diet Coke because it has more of these packed into the same amount of space.
What are particles?
