What affects the behavior of gases more than it affects solids and liquids?
Color and mass
Shape and size
Changes in temperature, pressure, and volume
Chemical properties
What does the kinetic molecular theory explain?
How to measure pressure
How particles in matter behave
Why solids are dense
How volume changes with shape
According to the kinetic molecular theory, what are all matter made up of?
Atoms
Molecules
Small particles
Elements
What kind of motion are particles in?
Circular motion
Constant, random motion
Slow motion
Vibrational motion
When particles collide with other particles, objects, or container walls, what happens to energy?
It doubles
It is lost
No energy is lost
It creates light
What is pressure?
The number of particles in a substance
Amount of force applied per unit of area
The size of a gas container
The speed of particles
What happens when particles collide with their container?
The particles freeze
The gas turns to liquid
Pressure results
The temperature decreases
What happens to the plunger when weight is added to it?
It lifts
It compresses the gas in the cylinder
It evaporates
It cools the gas
When particles have less space to move, what happens?
Pressure decreases
Particles disappear
Particles collide more frequently and pressure increases
Volume becomes zero
What causes an increase in pressure in a gas?
Decreasing the number of particles
Heating the gas
Compressing the particles
Expanding the container
What happens when volume increases?
Particles collide more frequently
Pressure increases
Particles have more room to move and pressure is less
Volume turns into mass
What happens when volume decreases?
Pressure is greater
Pressure is less
Particles move apart
Particles stop moving
What does Boyle's Law state?
Temperature increases when pressure increases
Pressure of a gas increases if the volume decreases and pressure of a gas decreases if the volume increases, when temperature is constant
All gases have the same volume
Volume and temperature are not related
In Boyle's Law, what do P1 and V1 represent?
Final pressure and volume
The temperature and volume
The pressure and volume before a change
Initial temperature and pressure
What is the unit of pressure in Boyle's Law?
Newton
Pascal
Kilopascals (kPa)
Degrees Celsius
What happens to the air pressure inside your middle ear on the ground?
It becomes less than outside pressure
It equals the air pressure surrounding you
It increases
It causes a headache
What happens to the surrounding air pressure when an airplane takes off?
It increases
It stays the same
It decreases
It doubles
Why can airplane travel cause ear pain?
Air pressure outside becomes greater than inside
Trapped air in the middle ear increases in volume
There is no air in the cabin
The air becomes hotter
In the graph of Boyle's Law, what happens when pressure increases?
Volume increases
Volume decreases
Volume remains constant
Temperature increases
What else affects gas behavior besides pressure and volume?
Color
Shape
Changing the temperature
Adding mass
What happens at low temperatures?
Average kinetic energy is high
Particles move farther apart
Volume increases
Average kinetic energy is low and particles move closer together
What happens when thermal energy is added?
Particles move slower
Pressure decreases
Gas particles move faster and spread farther apart
The plunger is pulled down
What law states that volume of a gas increases with increasing temperature, if the pressure is constant?
Boyle's Law
Newton's Law
Pascal's Law
Charles's Law
What happens to a balloon on a cold winter day?
The gas inside expands
The balloon heats up
Temperature decreases, kinetic energy decreases, gas particles slow down and volume decreases
It floats higher
What happens when the balloon is returned to a warm place?
Volume decreases
Kinetic energy increases and volume increases
Gas condenses
Pressure decreases
What does it mean when a graph is extrapolated?
It is made using fake data
It is only used in chemistry
It is extended beyond the observed data points
It has no units
What happens to the volume of a gas as temperature increases at constant pressure?
Volume decreases
Volume stays the same
Volume increases
Volume turns to solid
What is the temperature at which matter has the lowest possible energy state?
0°C
273 K
Absolute zero
Freezing point
What is the value of absolute zero in kelvin?
273 K
0 kelvin
100 kelvin
-100 kelvin
What happens to particles at absolute zero?
They move rapidly
They melt
They are at the lowest possible energy state and do not move
They change to solid
