Observations can be qualitativeor quantitative. What is thedifference? Hypothesis is a possibleexplanation for an observation.
Theory is a set of tested hypothesesthat gives an overall explanationof some natural phenomenon.Explains WHY.
Law is a summary of observedmeasureable behavior.Summarizes WHAT.
Prefixes are commonly used to change the size of a unit.
You must memorize this table.
There is always some degree ofuncertainty in a measurement. The degree of uncertainty isdependent on the measuringdevice. It is important to indicate theuncertainty in any measurement. This is done by recording certaindigits and the first uncertain digit. These numbers are called significantfigures.

0.01 mL
Nonzero integers are significant.
Zeroes:
(i) Leading Zeroes (precede nonzero
integers) are not significant.Example: 0.0025Answer:
(ii) Captive Zeroes (zeroes sandwiched
between integers) are significant.Example: 1.008Answer:
(iii) Trailing Zeroes (zeroes after integers) are
significant only if the number contains adecimal point.Examples: 100; 1.00 x 10
3
Answers:
contain an infinite number of significant figures.Example: 10 experiments or 3 cats
