This state of matter has a definite volume but no definite shape.
Liquid
The phase change when a solid turns into a liquid.
melting
This is released to the surroundings when water vapor undergoes condensation to form liquid water.
Thermal Energy
The movement of particles in a solid.
vibrating in a fixed position
How many states of matter are represented on the graph? Name them.
Two; Liquid and Gas
This type of solid has particles that are randomly scattered.
Amorphous solid
The phase change when a gas turns into a liquid.
condensation
What is thermal energy doing during to the particles on the horizontal flat line on a heating curve. What does the horizontal line represent?
Particles are breaking apart and a change in state of matter
Particles in a gas compared to a liquid or solid.
moving randomly and rapidly with large spaces between them
How many phase changes/changes in states are represented on the graph?
1
The total energy of all the particles within an object.
Thermal Energy
The phase change where a gas turns directly into a solid, forming frost.
deposition
Particles with more mass will move this way compared to particles with less mass, assuming they have the same amount of kinetic energy.
Slower
This term describes a fluid's resistance to flow (e.g., honey has a high one).
viscosity
How long did the vaporization process take?
10 minutes
This type of solid, like ice, has particles arranged in a specific, repeating pattern.
Crystalline Solid
The phase change where a solid turns directly into a gas, like dry ice.
sublimation
This process, which is the opposite of melting, requires a substance to release thermal energy to the surroundings.
Freezing
The reason a gas has no definite volume and will fill its entire container.
particles have enough energy to overcome all attractive forces and break apart
From the time it started heating, how many minutes did all of the liquid acetone take to become a gas?
30 minutes
The temperature at which a crystalline solid changes into a liquid.
melting point
The process that is the opposite of melting.
freezing
This property, which is a measure of the average kinetic energy of the particles, does not change during a phase change.
Temperature
For a pure substance, the reason its melting point and freezing point are the same temperature
The temperature, the solid and liquid states are in equilibrium
Name all six changes is sates (phase changes) and what states they between.
Melting: Solid → Liquid
Freezing: Liquid → Solid
Vaporization (Boiling/Evaporation): Liquid → Gas
Condensation: Gas → Liquid
Sublimation: Solid → Gas (skips the liquid phase)
Deposition: Gas → Solid (skips the liquid phase)
