100
What are the 3 states of matter
solid, liquid, & gas
100
Define kinetic energy
the energy of motion
100
What is the definition of temperature?
The measure of the average kinetic energy
100
What is pressure?
amount of force per unit area or particle collisions with the wall of their container or each other
100
a rock is what state of matter
solid
200
Describe the structure of a solid, what is the spacing of the particles and how are they moving?
Solids have a rigid structure, their particles are very close and they are vibrating in place
200
How do we think about potential energy in 7th grade?
Potential energy is still stored energy but it is no longer "not moving" potential energy in particles is determined by their potential to change
200
What happens to particles when matter condesates?
the particles get closer together and slow down
200
What would happen to the particles in a gas as you increase pressure?
particles would move closer together
200
In a food pyramid what happens to the energy as you go up?
10% goes to the next consumer, 90% is lost to the environment
300
properties of matter include whether or not you can change the volume and/or shape.
Which state of matter can you change one but not the other?
Liquid. You can change the shape but not the volume
300
What does intramolecular forces mean? Which state has the strongest?
the attraction between particles/molecules
Solids have the strongest
300
If we increased the temperature on a solid what would happen to the particles? What phase change is this?
Particles would move away from each other. This is melting
300
The point where all three states of matter coexist
What is the triple point?
300
What are three ways atoms combine?
elements, compounds, mixtures
400
What are the particles like in a gas? How does this help you change the volume of a gas?
Particles are very spread out and moving fast. As you add heat particles can easily spread out more and change the volume
400
Which of these substances has the weakest intermolecular forces?
a. melted steel
b. a cube of aluminum metal
c. argon gas
d. salt water
c. argon gas
400
Which phase change is occurring here?
Sublimation

Madi bought a balloon for her daughter's birthday and then left them in the car on a hot day.
The balloon popped.
What happened to the particles and pressure that caused this to happen.
As heat was added to the balloon the particles started moving faster and farther apart. Eventually the balloon could not contain the particles anymore and popped.
400
What is the smallest unit of life?
a cell
500
Model the three states of matter.
Models must be labelled, neat, and include movement lines
500
What is the difference between a solid and a gas at room temperature? Who has stronger intermolecular forces? Who has more potential/kinetic?
a solid's particles are closer together because they have a stronger intermolecular forces. Because of this they have lower potential and kinetic energy
500
Below is a phase diagram of an unknown substance. What could be concluded from the portion of the graph between letters D and E, where the temperature remains constant?
The unknown substance is going through the phase change vaporization or condensation
500
At what temperature and pressure is the triple point for carbon dioxide based on this diagram
Temp: -56.4° C
Pressure: 5.2 atm

In 2019 Taylor Swift expressed disappointment that the masters of her first 6 albums were sold to Scooter Braun, someone she did not like, instead of her. Who sold him the masters?
Scott Borchetta/Big Machine Records
