12. liter standard metric unit of length

Explanation:

• Significant figures: By definition, these are the digits in a number that have true value.
• Experimentation: It involves doing repeated tests to verify a hypothesis.
• Metric system: It is a system of measurement based on the number ten.
• Exponent: It is the number of times a base number is multiplied times itself, shown as a superscript.
• Hypothesis: It is a possible answer to a scientific problem.
• Meter: It is the standard metric unit of length.
• Scientific method: It consists of ordered steps a scientist uses in his or her work.
• Second: It is the standard unit of time.
• Law: It is a scientific fact which provides repeatable results and has never been falsified.
• Scientific notation: It is a system of writing numbers as a multiple of a power of 10.
• Theory: It is a suggested or proposed solution to a general scientific area of inquiry.
• Liter: It is the standard metric unit of volume.
