Properties and classification of Matter
The three states of matter
What is liquid, solid, and gas?
The phase change from liquid to solid
We use scientific notation because
What is, its a way to write really big or really small numbers.
The definition of accuracy
What is how close a measurement is to the true value?
What is tightly packed (solids), close (liquids), and far apart (gas)?
The phase change from liquid to gas
This number written in scientific notation: 600,000,000
What is 6 × 10⁸
The units of density
g/cm3 or g/mL
The definition of precision
What is how close repeated measurements are to each other?
The classification of oxygen
What is an element?
The phase change from gas to liquid
What is condensation?
The equation for precent uncertainity
What is uncertainty/measurement multiplied by 100
The density of water is
What is 1.0 g/mL?
You measure a blocks density 3 times, the true density is 7.9 g/cm3 Your results are 5.8 g/cm3, 5.9 g/cm3, 6.0 g/cm3. Our results are...
What is precise?
The classification of air
What is a homogenous mixture?
The phase change from gas to solid
What is deposition?
To reduce uncertainty in our measurements
What is (multiple answers apply)?
Icebergs float because solid water...
What is less dense than liquid water?
The uncertainty associated with measurement 12.1 cm
What is ± 0.1 cm
The type of element C2 is
A diatomic atom
The phase change from solid to gas
What is sublimation?
Scientist use percent uncertainty to
What is show how reliable their measurements are?
Oil floats on water...
What is it's less dense?
We used the same tool, got the same uncertainty, but the percent uncertainty changes...
What is depending on the size of the substance. Small objects have greater uncertainty while larger objects have a smaller uncertainty.
