I. Identify The Different Changes in The Phases of Matter: Example

The document describes the different phases of matter and changes between them. It identifies 8 phases: solid, liquid, gas, plasma and the changes between them - melting, freezing, vaporization, condensation, deposition, sublimation, ionization, and recombination. Each change is defined by its starting and ending phase. Examples are provided for each change, such as the melting of ice or the condensation of water vapor into dew.

I.

Identify the different changes in the phases of matter


a. MELTING
Solid -> Liquid
Example : Melting of an ice cube into
water

b. FREEZING
Liquid -> Solid
Example : Freezing sweetened
cream into ice cream

c. VAPORIZATION
Liquid -> Gas
Example : Evaporation of alcohol into its vapor.

d. CONDENSATION
Gas -> Liquid
Example : Condensation of water vapor
into dew drops.
e. DEPOSITION
Gas -> Solid
Example : Deposition of silver vapor in a vacuum chamber
onto a surface to make a solid layer for a mirror.
f. SUBLIMATION
Solid -> Gas
Example : Sublimation of dry
ice (solid carbon dioxide) into
carbon dioxide gas

g. IONIZATION
Gas -> Plasma
Example : Ionization of particles
in the upper atmosphere to form
the aurora.

h. RECOMBINATION
Plasma -> Gas
Example : Turning off power to a neon light, allowing the
ionized particles to return to the gas phase.

II. Give the distinct characteristic of each change


Freezing occurs when a liquid changes to a solid.
Melting occurs when a solid changes directly to a liquid.
Sublimation occurs when a solid changes directly to a gas.
Deposition occurs when a gas changes directly to a solid.
Condensation is when a gas changes directly to a liquid.
Vaporization happens when a liquid changes directly to a gas.
Ionization occurs when a gas changes to plasma.
Recombination occurs when plasma changes to gas.

III. Write 2 concrete examples to each change


=MELTING=
a. Butter melts in a frying pan.
b. Candle wax melts in the heat of the candle’s flame.
=FREEZING=
a. Water to ice - Water becomes cold enough that it turns into
ice. In fact, every known liquid (except for helium) is known to
freeze in low enough temperatures.
b. Liquid to crystals - Most liquids freeze by a process that is
known as "crystallization," whereby the liquid forms into what is
known in the scientific world as a "crystalline solid."
=VAPORIZATION=
a. Water to steam - Water is vaporized when it is boiled on the
stove to cook some pasta, and much of it forms into a thick
steam.
b. Water evaporates - Water evaporates from a puddle or a pool
during a hot summer’s day.
=CONDENSATION=
a. Water vapor to dew - Water vapor turns from a gas into a
liquid, such as dew on the morning grass.
b. Water vapor to liquid water - Water vapor fogs up glasses
when moving into a warm room after being in the cold
=DEPOSITION=
a. Water vapor to ice - Water vapor transforms directly into ice
without becoming a liquid, a process that often occurs on
windows during the winter months.
b. Physical vapor to film - Thin layers of material known as
"film" are deposited onto a surface using a vaporized form of the
film.
=SUBLIMATION=
a. Dry Ice - Solid carbon dioxide is known as "dry ice" and
sublimates at room temperature.
b. Freeze-drying - Water can be sublimated in a food product by
using a vacuum.
=IONIZATION=
a. Aurora
b. Nebula
=RECOMBINATION=
a Turning off power to a neon light, allowing the ionized particles
to return to the gas phase.
