Particle Basics
What are are all substances made of according to kinetic molecular theory?
Particles/Molecules
What state of matter has particles packed closely together vibrating in place?
Solid
Temperature is a measure of the average ________ energy of particles
Kinetic
Gas pressure is caused by particles _________ against the wall of the container
Colliding / Bumping into each other
A balloon is being heated, the particles inside move faster. What idea of KMT does this demonstrate?
Increases in temperature also increases kinetic energy
True or False particles are always moving on earth?
True
What state of matter has particles that are close together but can slide past each other?
Liquid
If you put a balloon into a warm room what happens to the movement of gas particles inside?
They move faster
What happens to gas pressure if the particles are colliding and Bumping into each other more often?
The pressure increases
Why can you compress gas easily but not a solid?
Gas particles have lots of space in between then
What happens to particles when temperatures raise?
They move faster
What state of matter has particles that are far apart and move freely?
Gas
Which has faster moving particles a cup of ice water or a cup of hot water?
The cup of hot water
If you squeeze a gas into a smaller container do its particles have more or less room to move?
Less room
A puddle of water disappears on a hot day. What happens to the water particles?
Some gain enough energy to escape into the air and become a gas
What happens to particles when temperature decreases?
They move slower
Which state of matter has the most particle movement?
Gas
Why does the smell of food spread faster when the food is hot?
The particles move faster and spread out quicker
Why does squeezing a gas into a smaller container usually increases the gas pressure?
The particles hit the wall of the container more often
Container B
According to Kinetic Molecular Theory do particles attract each other?
Yes, particles have attraction forces between them
If you heat a solid enough its particles move faster until it changes into what state?
Liquid
If the temperature of a gas increases what happens to the kinetic energy of the particles?
It increases
Imagine you are pumping air into a basketball. What happens to the pressure inside as you add more air?
The pressure increases as there are more particles colliding inside the basketball?
A balloon is placed in the freezer. What happens to the gas particles inside the balloon, and how does this affect the balloon?
The particles move slower, collide less with the walls, and the balloon shrinks
