Chapter 1
This science is the study of matter and the changes it goes through.
Chemistry
This value is required in order to calculate Density.
Mass OR Volume
A derived unit is made up of this many SI units.
2 or more
Matter that as a definite composition is called what?
A substance
The type of change that occurs when ice turns to water.
physical change
An example of a qualitative measurement.
color OR hardness OR taste
This is what happens to your mass when you are farther away from the Earth's surface
Mass remains constant
An example of a homogeneous mixture.
The state of matter with an indefinite shape but a definite volume
liquid
This part of the experiment serves as the point of comparison for the results
The density of a substance that has 26.94 grams and 2.568 liters
10.49 g/l
This term describes the amount of mass contained per unit volume
density
This is the name of the change of state for when a gas becomes a liquid
condensation
An example of an intensive physical property
color
This household appliance increases the amount of chlorofluorocarbons in the atmosphere
Refrigerator
A temperature of 273 degrees Celsius equals this much Kelvin.
546 K
This type of graph is best to visualize data across multiple categories
Bar graph
This mixture separation technique relies on the different boiling points of the parts of the mixture
distillation
This law states that a compound is always composed of the same elements in the same proportion by mass
This is scientific notation of 0.00000079
7.9 x 10^-7
This is the density for a 45 grams of a substance in 180 liters of another substance
0.25 g/L
Circle - to show percentages
Bar - to show data across categories
Line - to show data of 2 variables
This type of mixture is a chemical composition of two or more different elements joined together in fixed proportions
compound
This is the difference between a gas and a vapor
A gas is a gas at room temperature
A vapor is a solid or liquid at room temperature
