IC1 Vocabulary
What is Mass
The number of particles that are in an object.
Explain the shape and volume of a liquid
Liquids have no fixed shape but, they do have a fixed volume
This matter has a fixed shape and a fixed volume
What is a solid
What is compression?
To press or squeeze matter into a reduced volume/space and to increase pressure.
The amount of space that an object’s particles take up.
Volume
Explain the shape and volume of a gas
They have no fixed shape or volume.
This matter has particles that can slip and slide past each other
What is a liquid
When particles of matter spread out into an enlarged space and fill the area is ____________________.
Expand/expansion
List the 3 Phases/States of matter
The 3 phases/states of matter; solid, liquid, and gas.
What phase must an object be in to be smelled by your nose? explain
It must be in the gas form to move fast and freely to be able to enter your nose for you to smell it.
This matter has a weak attraction force between its particles.
If you compress a gas, how do the particles move inside of its container?
They will still move fast and freely in the container even though they are compressed.
The decrease in volume of any object by squeezing the particles together through pressure
compress/compression
List all of the phase changes (5)
Condensation, freezing, melting, vaporization, and sublimation
This type of matter has particles that only vibrate in place when disturbed.
What is a solid.
Draw a model of compressed gas
See teacher board
What is Expand/Expansion
An increase in the volume of a substance allowing particles to spread out (lowered pressure)
What causes an object to change it's phase?
List two types of matter that can take the shape of its container.
What is Liquids and Gases.
Draw a model of an expanded gas
