100
What are the properties of a solid. Hint: think of the particle arrangement and movement
Solids have rigid particles that vibrate in place. They have a definite shape and volume.
100
Is energy increasing or decreasing as you move from left to right?
Energy is increasing
100
Which segment has ONLY gas present in it
A-B
100
A mountain climber carries a sealed bag of chips to the top of a high-altitude mountain. What is most likely to happen to the bag as they ascend?
The bag will expand
200
What are the properties of a liquid. Hint: think of the particle arrangement and movement
Liquid particles slide over one another. They have a definite volume but indefinite shape
200
As you go from solid to liquid to gas to plasma, is it endothermic or exothermic?
Endothermic. You are absorbing energy.
200
In a heating curve of a substance, why does the temperature remain constant during a phase change, even though heat is still being added?
A. energy stops being absorbed during a phase change
B. heat added is used to break intermolecular forces rather than increasing energy
C. temperature decreases before rising slightly again
D. heat energy is lost to the surroundings, preventing a temperature change
B. heat added is used to break intermolecular forces rather than increasing energy

If you squeeze a balloon, what will happen to the volume?
Volume will decrease.
300
What are the properties of a gas. Hint: think of the particle arrangement and movement
Gas particles are far apart and free-floating. They have an indefinite shape and indefinite volume.
300
Which letter show an exothermic change?
B (condensing)
300
At what segments is the kinetic energy changing?
A-B, C-D, E-F
300
Which graph shows a direct relationship?
400
How is plasma difference from a gas?
Plasma has positive and negative ions
400
Which letter shows water turning into steam?
Letter D
400
True or False: The temperature changes at the same time the phase change occurs.
False! You cannot change the temperature and change your phase at the same time.
400
While looking at this picture, what happens to the pressure inside of the balloon?
Pressure will go up.
500
Which state of matter has MORE energy, ice water or water?
Water, because it has a higher temperature
500
Why does metal sink and wood float?
Metal is more dense than water and wood is less dense than water.
500
What is the melting point and the freezing point of this substance?
both are 100 degrees Celsius
500
Why does the volume of the bubbles increase as it travels to the surface?
Volume increases because the pressure decreases as you move towards the surface.
