States of Matter
Solid
When ice melts into water, it changes state but remains H2O, which makes this a _____ change
Physical
If an object is more dense than water, what will happen when it is placed in water?
It will sink
In a solution, the substance that is dissolved in the solvent is called
Solute
This is an everyday example of an acid
Citrus fruit (citric acid), vinegar, stomach acid, battery acid, etc.
This state of matter has neither a definite shape nor volume, with particles moving freely and spreading out to fill their container
Gas
This change happens when water boils and turns into steam, but no new substance is created
Physical (Evaporation)
Oil floats on water because it is ____ dense than water
Less
This type of mixture occurs when solid particles are dispersed in a liquid or gas but are large enough to settle over time
Suspension
When an acid dissolves in water, it produces this type of ions
Hydrogen (H+)
This type of solid has a random atomic arrangement
Amorphous
When a nail rusts over time, it’s an example of this type of change
Chemical
True or False? Solids are the most dense state of matter
True
These factors affect solubility
Temperature, pressure, stirring
When a base dissolves in water, it produces this type of ion
Hydroxide (OH-)
This is what occurs when water evaporates from the surface of a liquid and becomes a gas
Evaporation
The ability of a material to undergo a reaction that changes its structure to produce a new substance, such as when food is cooked
Chemical Change
The measure of how much mass is contained in a given volume of a substance
Density
This effect occurs when light is scattered by particles in a colloid or a suspension, making the beam of light visible
Tyndall Effect
This is an everyday example of a base
Baking soda, soap, bleach, ammonia, etc.
The process where a substance changes from a solid to a gas without becoming liquid first, such as dry ice turning into carbon dioxide gas
Sublimation
This property describes how easily a substance can catch fire or burn
Flammability
d=m/v
A solution that has dissolved the maximum amount of solute is
Saturated
What is produced in a neutralization reaction?
Water and salt
