States of Matter and Particle Motion
This state of matter has a definite shape and a definite volume.
What is a solid
Density, color, and flexibility are examples of these kinds of properties.
What are physical properties?
A substance made of only one kind of atom.
What is an element?
You place an object on this to determine its mass.
What is a balance (or scale)?
Bottles and bags are often made of this material built from carbon and hydrogen.
What is plastic (a polymer)?
This state has a definite volume but takes the shape of its container.
What is a liquid
Bubbling, new odor, or a new substance forming indicate this kind of change.
What is a chemical change?
A substance made of two or more different atoms chemically bonded.
What is a compound?
The volume of a regular box-shaped object is measured in these units (e.g., cm × cm × cm).
What are cubic centimeters (cm³)?
A polymer is made of many repeating small units called these.
What are monomers?
This state has no fixed shape or volume and expands to fill its container.
What is a gas
“Reacts with hydrochloric acid” is this kind of property.
What is a chemical property?
The smallest particle of a compound that still has its properties.
What is a molecule?
To find the volume of an irregular object, you can use water-level _______.
What is displacement?
Making, using, and disposing of a product describes its ______ cycle.
What is the life cycle?
As the temperature of water drops, the kinetic energy does this.
What is decreases
Hammering a metal into thin sheets tests this physical property.
What is malleability?
When hydrochloric acid reacts with calcium carbonate, the fizzing shows this gas forming.
What is carbon dioxide?
A substance that floats in water has a density that is this compared to water.
What is less than water’s density (less than 1 g/cm³)?
Choosing materials involves weighing pros and cons known as these.
What are trade-offs?
A balloon shrinking on a cold day shows that particles have less of this.
What is kinetic energy
A change where the substance keeps its identity (no new substance) is this.
What is a physical change?
In a balanced chemical reaction, this quantity is conserved.
What is mass (the law of conservation of mass)?
This formula finds density using two other measurements.
What is mass ÷ volume?
Re-processing aluminum instead of making it from ore saves lots of this resource.
What is energy?
