Everything in the universe is made of tiny, invisible building blocks called this.
What is a Particle?
This state of matter takes the shape of its container but keeps a fixed volume.
What is a Liquid?
The total amount of matter or "stuff" inside an object, usually measured in grams or kilograms.
What is Mass?
This property describes how tightly packed particles are within a given space.
What is Density?
We use a thermometer to measure this property, which tells us how hot or cold matter is.
What is Temperature
In this state, particles are locked in place and vibrate in a fixed spot.
What is a Solid?
This state spreads out completely to fill any container, changing both shape and volume.
What is a Gas?
The total amount of three-dimensional space an object takes up.
What is Volume?
An object will float in water if its overall density is ________ than the water.
What is Less?
Removing heat from liquid water drops its temperature until it turns into a solid, which is called ________.
What is Freezing?
As temperature goes up, particles gain energy and do this.
What is move faster (or spread apart)?
Solids maintain their exact form because their structure is fixed and ________.
What is Rigid?
If you pour water from a tall beaker into a wide glass, this property stays exactly the same.
What is Volume? (Or Mass)
The ability of a substance to be squeezed into a smaller volume.
What is Compressibilty?
Adding thermal energy to a solid causes its particles to vibrate faster until this phase change occurs.
What is Melting?
This state has particles that are close together but can slide past one another smoothly.
What is a Liquid?
When a solid turns into a liquid, its particles gain enough heat energy to change its ________.
What is State?
You measure this property of a liquid using a graduated cylinder in milliliters (mL).
What is Volume?
Why a heavy wooden log floats in a lake while a tiny pebble sinks to the bottom.
What is wood is less dense than water (or the rock is denser)?
Liquid water turns into gas (steam) when its temperature reaches this point.
What is Boiling Point?
The theory that states all matter is made of tiny, constantly moving pieces.
What is the Particle Theory of Matter?
Unlike liquids and gases, a solid keeps its original ________ no matter what container you put it in.
What is Shape?
Adding more particles to an object without changing its size will increase its ________.
What is Mass?
The state of matter with the highest compressibility because of large empty spaces between its particles.
What is a Gas?
Liquids cannot be easily squeezed because their particles are already jammed close together, giving liquids low ________.
What is Compressibilty?
