What is Matter? (Atoms & Mass)
Everything in the universe that has mass and takes up space.
What is matter?
The three classic states of matter on Earth.
What are solid, liquid, and gas?
The phase change from a solid to a liquid.
What is melting?
Characteristics used to describe, test, or observe an object (like color, texture, or hardness).
What are physical properties?
Chocolate milk is an example of this type of combined matter where substances blend evenly.
What is a solution?
The tiny, building-block particles that make up all matter.
What are atoms?
This state of matter has a definite shape and a definite volume because its particles are tightly locked and only vibrate.
What is a solid?
The process of a gas turning into a liquid (such as water drops forming on the outside of a cold glass).
What is condensation?
An object that floats in water has this relationship to water's density.
What is less dense than water?
A physical combination of two or more substances where each keeps its own identity and can be separated easily.
What is a mixture?
If you break a 12-gram wooden block cleanly in half, this is the mass of one piece.
What is 6 grams?
In this state of matter, particles are spread very far apart and move around very quickly.
What is a gas?
This form of energy is added or removed to cause matter to change from one phase to another.
What is thermal energy (or heat)?
These three metals are famously magnetic, unlike most other metals.
What are iron, nickel, and steel?
When you dissolve sugar in water, the sugar particles break apart and become too small to see, meaning the total mass of the solution does this.
What stays the same (or equals the mass of the water plus the sugar)?
Even though you cannot see it, an inflated soccer ball weighs more than a deflated one because air is made of this.
What are particles / matter / gas particles?
This state of matter takes the shape of its container while keeping the same volume and being able to flow.
What is liquid?
Adding heat causes particles to speed up and spread out; removing heat causes particles to do this.
What is slow down and move closer together?
Materials that allow heat to move through them easily are called thermal what?
What are conductors?
An ingredient or substance that helps unmixable liquids (like oil and water) mix together.
What is an emulsifier?
This law states that matter cannot be created or destroyed during a physical or chemical change.
What is the Law of Conservation of Mass?
This high-energy state of matter consists of electrically charged gas and is found in lightning and the sun.
What is plasma?
When liquid water turns into invisible water vapor at the surface below its boiling point, it is called this.
What is evaporation?
This formula is used to calculate the density of an object.
What is Mass divided by Volume (D = M/V)?
This laboratory method uses paper and a solvent to separate mixed colors or pigments.
What is chromatography?
