Phases Changes
Randomness
100
Particles vibrating in fixed locations.
What is a solid.
100
its temperature, its volume, and number of particles
What are the three things that affect the pressure of an enclosed gas?
100
Result of a force distributed over an area.
What is pressure?
100
A reversible physical change that occurs when a substance changes from one state of matter to another.
What is a phase change? DAILY DOUBLE Draw the triangle diagram, and correctly label ALL six phase changes...
100
The arrangement of molecules becomes less orderly as this happens.
What is water melting.
200
Classified by whether their shapes and volumes are definite or variable.
What are states of matter?
200
Temporary increase in volume allows the particles to spread out, which lowers the pressure. Now the pressure outside is greater, and air rushes in.
What is inhaling? DAILY DOUBLE Which law is this a representation of?
200
Raising this will increase its pressure if the volume of the gas and the number of particles are constant.
What is temperature?
200
This does not change during a phase change.
What is temperature?
200
An exothermic change.
What is freezing? DAILY DOUBLE Name an endothermic change.
300
Particles can flow to new locations, but are held together by forces of attraction.
What is a liquid?
300
an ideal gas cooled to -273.15 *C
What is absolute zero? A.K.A. 0 Kelvin
300
Reducing this will increase the pressure if the temperature and the number of particles remain constant.
What is volume?
300
energy absorbed and energy released
What is endothermic and exothermic.
300
Particles speed up and spread apart.
What are heated particles inside a balloon?
400
Particles are in constant random motion, unaffected by other particles unless the particles collide.
What is a gas?
400
Particles in the air squeezed into a smaller volume and the pressure increases to greater that outside, air is forced out.
What is exhaling?
400
Increasing this will increase the pressure of a gas if the temperature and the volume are constant.
What are the number of particles?
400
The greater the surface area, the faster this.
What is evaporation? DAILY DOUBLE Define evaporation.
500
Kinetic theory of matter says that all particles of matter are this.
What is constant motion?
500
This causes the particles in a gas to fill a container of any size.
What is constant motion?
500
Allows water to flow, but not fill container.
What are forces of attraction?
500
The more frequent the collisions, the greater this is.
What is pressure?
500
one factor affecting another within a gas law
What is teacher will answer. DAILY DOUBLE Give an example of the other.
