States of Matter
If a particle does not move but vibrates what state is it in
Solid
If a liquid is spilled what direction do the particles go
Down/spills
Define vibrating
When something moves back and forth
When a liquid turns into a solid what type of change is it called
Freezing
What is matter made of
Atoms
(Albert)
If a particle moves but stays together with other particles, what type of state is this?
Liquid
If a gas escapes a container where do the particles go
They go up
(Super round) Define thermal energy
Total kinetic & potential energy of all the particles in something
(Tornado)
When a liquid turns into a gas what type of change is this
Evaporation
What properties describe matter
Physical and chemical properties
(Super round) What state of matter has the least amount of energy
Solids because it does not move a lot (Tornado)
What does particles look like when they are Amorphous
They looks messy/no defined shape or form
What is a molecule
A group of atoms bonded together, At least 2
When a gas turns into a liquid what type of change is this
Condensation
If a nail rusts what change is this
Chemical change
What type of state is something in when it moves freely around and goes up
Gas
(Super round) If heat is added to particles there are ____ vibrations, but if it gets colder there are ______ vibrations
Bigger, Little
Tornado
(Super round) Define Freezing point
The temperature at which something freezes
(Nikola)
Is thermal energy an example of changes of state, Name all changes of state for 800 (optional)
No, Vaporization, Evaporation, Condensation, and Sublimation
(Super round) Is gold a molecule or a element
trick question, its both
(Nikola)
(Super round) Define a Solid, For extra 500 define Viscosity
A solid has a definite shape and a definite volume, (tornado)
A resistance to flowing
(Super round) What happens to a particle when it is heated and when it is getting cold/freezing
Heat-
Cold/freezing-
Particles move faster
Particles slow down
(Albert)
What occurs when the surface particles of a solid gain enough energy that they form a gas
Sublimation
(Super round) If you leave dry ice in the open for a couple hours what type of change is this
Sublimation (Nikola)
(Super round) What happens when mass is conserved
matter does not get created or destroys so it stays the same
(Tornado)
