100
State of matter that has definite volume, but not definite shape.
What is liquid?
100

energy is measure in ___________

What is Calories

100
The place on a phase change graph with horizontal line.
What is where a phase change is actually happening?
100
What are the three states of matter?
Solid, Liquid, & Gas
100
Particles are stuck in place and cannot flow.
What is Rigidity?
200
Heat transfer method due to currents in fluid.
What is convection?
200

Transfer of heat energy uses what formula?

What is calories = mass x temp change

200
What is happening at the horizontal line at boiling point.
What is boiling / vaporization?
200
State of Matter with the highest kinetic energy of particles.
What is Gas?
200
It is definite in solids and liquids.
What is volume?
300
The phase change from solid to gas without a liquid phase.
What is sublimation?
300

In order to calculate a temperature change using the formula temp change = final temp - initial temp what is required?

What is same volume for each temperature.

300
What is changing at the diagonal lines on a phase change graph.
What is Temperature?
300
State of matter with Rigidity and no Fluidity.
What is a solid?
300
This is definite for all states of matter
What is mass?
400
The scientific point at which freezing and melting both occur.
What is the melting point?
400

If I have 100 mL of 5 degree water and 100 mL of 45 degree water, what will the final temperature be when I mix them together?

25 degrees

((5 + 45)/2)

400
What is not changing at the diagonal lines on a phase change graph?
What is state of matter?
400
State of matter where particles can slide past each other.
What is Liquid?
400
How fast particles move in matter.
What is Particle Kinetic Energy?
500
Frost is an example of this phase change.
What is deposition?
500

If a student has two water samples, both are 50 mL, and one has a temperature of 50 degrees Celsius and the other has a temperature of 70 degrees Celsius, how much energy was transferred from the hot water to the cold?

50 + 70 = 120

120/2 = 60 degrees

calories = mass x change in temp

calories= 50g x (60-70) degrees

calories = -500

500
This increases due to the addition of heat.
What is kinetic energy of particles?
500
State of matter where storage requires a closed container.
What is Gas
500
Travels from areas of high concentration to areas of low concentration.
What is Diffusion?
