Properties of Matter
Solid matter has a/an ___________________ (definite/indefinite) Volume and a/an ____________________ (definite/indefinite) Shape.
Definite; Definite
True or False? Leading zeros do not count as Significant.
True
When completing a Pressure Conversion, what do you always write in Fraction #1?
Measurement given over 1.
As the Volume increases, what happens to the Pressure?
Pressure decreases
Which variable never changes in the Ideal Gas Law?
R
Liquid matter has a/an ___________________ (definite/indefinite) Volume and a/an ____________________ (definite/indefinite) Shape.
Definite; Indefinite
When do Trailing Zeroes count as significant?
When there is a Decimal Point in the measurement.
When can you cancel units in a Pressure Conversion?
Describe the relationship between Pressure and Volume according to Boyle's Law.
There is an inverse relationship. If Volume increases, then Pressure decreases and vice versa.
What are moles used to measure?
The quantity of atoms/molecules/particles of small substances.
Gas matter has a/an ___________________ (definite/indefinite) Volume and a/an ____________________ (definite/indefinite) Shape.
Indefinite; Indefinite
How many Sig Figs (SF) are in this measurement: 6,030 mm?

How do you know if there are 2 fractions in the Pressure Conversion?
If the units you have been given in the Problem and the units you are solving for are on the same line of the "Pressure Conversions" chart.
Accuracy: Measurement of how close the measurement is to the accepted or correct value of quantity being measured.
Precision: Measurement of how close a series of Measurements are to one another.
Describe the State of Matter on the Melting Point line of a Heating Curve (Line B on today's Warm-Up).
Matter is transitioning from a Solid to a Liquid. The further to the right you move on the line, the higher the percentage of Liquid and the lower the percentage of Solid..
How many Sig Figs (SF) are in this measurement? 600,000,500
7
How do you know if there are 3 fractions in the Pressure Conversion?
If the units in the measurement given to you in the problem and the units you are converting to are NOT on the same line of the "Pressure Conversions" chart.
3 Darts are thrown at a Dartboard. They all hit in different positions away from the Bullseye. This is an example of ____________ (high/low) Precision and ___________ (high/low) Accuracy.
low; low
Describe the State of Matte on the Boiling Point line of a Heating Curve (Line D in today's Warm-Up).
Matter is transitioning from a Liquid to a Gas. The further to the right on the line, the higher the percentage of Gas in the Matter and the lower the percentage of Liquid.
How many Sig Figs (SF) are in this measurement: 0.000000850000310500 cL?
12
