|
|
|
The way a substance reacts with an other.
|
chemical property
|
|
|
property that can be observed without changing the identity of a substance.
|
physical property
|
|
|
____ is the change of a liquid into a gas below the boiling point.
|
evaporation
|
|
|
__________ is the changing of a gas into a liquid.
|
condensation
|
|
|
the measure of how much space matter takes up.
|
volume
|
|
|
the measure of the amount of matter.
|
mass
|
|
|
the amount of a matter in a certain volume of a substance; found by dividing the mass of an object by its volume.
|
density
|
|
|
the smallest unit of an element that has the properties of that element.
|
atom
|
|
|
the process of changing directly from a solid to a gas without first becoming a liquid.
|
sublimation
|
|
|
the center of an atom that has most of its mass.
|
nucleus
|
|
|
a particle that has more than one atom joined together.
|
molecule
|
|
|
is a method of separating mixtures based on differences in volatilities of components in a boiling liquid mixture.

|
Boiling point: 212 degrees F
Freezing point: 32 degrees F |
|
|
What is the difference between physical and chemical property?
|
Physical properties can be observed without the identity of it changing, while chemical properties' identities change when observed.
|
|
|
List some examples of physical AND chemical property.
|
Physical property: Weight, mass, and volume change.
Chemical Property: burning a log, a rusting nail, exploding fireworks |
|
|
What is the formula of density?
|
Mass divided by volume.
|
|
|
Explain the addition and loss of energy/heat when matter changes from solid to gas.
|
temperature increases,heat is absorbed and energy increases and is absorbed.
|
|
|
What are the phases in the changes of matter?
|
Solid to liquid: Melting Point
Liquid to Gas: Evaporation Gas to liquid: Condensation Liquid to solid: Freezing point Solid to gas: Sublimation |
|
|
What are the factors that cause water to: freeze, melt, or evaporate at different rate.
|
Evaporation factor: Increase of heat.
Freeze factor: Decrease in heat. Melt factor: Increase of heat. |
