(20 cards)
Why is it that when we climb higher on Mount Fuji, the air begins to become colder and thinner?
B/c when we go higher altitude increases which means the amount of gas molecules in the air decreases making it difficult to absorb heat
If the air in the flask is heated, the volume of the air will _________ and the ballon will ______.
Increase/Expand
If the air in the flask is cooled, the volume of the air will ________ and the balloon will _________.
Decrease/Shrink
What happened to the balloon as the flask was first heated and then cooled?
The balloon expanded when the flask was heated and then shrunk when it was cooled
What determines the phase of matter?
The motion and speed of particles
What is matter made of?
Particles
What is plasma?
Like a gas, plasma has no shape or volume
What are the particles in plasma like?
They are broken down
How is plasma formed?
When electricity is passed through gas
True or False: Plasma can glow
True
The particles within a solid are very close together and vibrate in a _________ position.
Fixed
Liquids have a fixed volume but have a _________ shape.
Variable
Gas particles are in constant motion at _________ speed, and, therefore, they are spaced far apart.
High
Gases have a __________ shape and volume because they can be compressed under pressure.
Variable
Which objects are the easiest to pull apart: wood block, plastic spoon, paper, paper clip, or clay?
Sheet of paper and clay
Which objects were the hardest to pull apart: wood block, plastic spoon, paper clip, clay, or sheet of paper?
Wood block, paper clip, and plastic spoon
What is holding the particles in the objects together?
Particle attraction
Why are the glass, water, and air in different states of matter at the same temperature?
B/c they have different levels of particle attraction
What increases as well when the temperature increases in a solid, liquid and gas?
The attraction between particles
Pressure is the force exerted by a substance on its container. Of the three states of matter - solid, liquid, and gas, which one would exert the highest pressure on its container? Why?
Gas b/c the particles in the substance are constantly moving freely
