Vocab
This is anything that has mass and takes up space.
This state of matter has a definite shape and particles are slowly moving
What is a solid?
This phase change happens when a solid becomes a liquid.
What is melting?
When temperature increases, particle motion generally does this.
Move faster
You can measure how much space an object takes up. What property are you measuring?
What is volume
This is the amount of matter in an object.
What is Mass?
This state has a definite volume but takes the shape of its container particles are moving at a medium speed.
What is a liquid?
This phase change happens when a liquid becomes a solid.
What is freezing?
In a solid, particles are packed closely together and do this in place.
Move slow
Ice sitting on a warm countertop slowly becomes liquid. What phase change is occurring?
What is melting
This is the amount of space that matter takes up.
What is volume
This state of matter does not have a fixed volume and the particles have a lot of energy.
What is a gas?
This phase change happens when a liquid becomes a gas at the surface of a liquid.
What is evaporation?
If you add thermal energy to a substance, what happens to its particles?
They move faster
A cup of water is placed in a freezer. What happens to the particle motion as the water freezes?
It slows down
These are the tiny building blocks that make up all matter.
What is an Atom?
Name all three common states of matter.
What is a solid Liquid and a gas
The name of Mrs.Matthias' daughter
WHo is parker jo?
If particles are moving slower, what is happening to the system?
The system is losing thermal energy or getting colder
I have a beach ball and a small dog which one has more matter inside? aka more mass
What is a dog?
This is made when two or more atoms are joined together.
What is a molecule?
Explain how the particles are arranged and moving differently in a solid, liquid, and gas.
slow medium fast
This phase change occurs when a solid changes directly into a gas without becoming a liquid first.
What is sublimation?
If salt makes ice melt faster what must salt be helping add to the system?
What is a warmer temperature or an increase in thermal energy
A solid is heated until it becomes a gas. Describe what happens to the particles as the substance changes state.
They gain energy and move faster and get more spread out
