Matter
What is an atom?
The amount of space occupied by an object.
length x width x height
What is volume?
Combination of substances with a composition that varies from point to point.
What is a heterogenous mixture?
A combination of substances with a composition that is uniform throughout.
What is a homogenous mixture?
A versatile mathematical approach that can be applied to computations ranging from simple unit conversions to more complex, multi-step calculations.
What is dimensional analysis?
A homogeneous substance that has a constant composition.
What is a pure substance?
The estimate of amount by which measurement differs from true value.
What is uncertainty?
Property of a substance that is independent of the amount of the substance.
What is an intensive property?
A change producing a different kind of matter from the original kind of matter.
What is a chemical change?
When matter converts from one type to another or changes form, there is no detectable change in the total amount of matter present.
What is the Law of Conservation of Matter?
What is the first Law of Thermodynamics?
A pure substance that can be decomposed into two or more elements.
What is a compound?
Used to measure amount of substance.
What is a mole?
Change in the state or properties of matter that does not involve a change in its chemical composition.
What is a physical change?
The property of a substance that depends on the amount of the substance present.
What is an extensive property?
The ratio of mass to volume for a substance or object.
What is density?
A bonded collection of two or more atoms of the same or different elements.
What is a molecule?
Standard metric and SI unit of length.
This describes how closely a measurement aligns with a correct value.
What is accuracy?
This describes how closely a measurement matches the same measurement when repeated.
What is precision?
The path of discovery that leads from question and observation to law or hypothesis to theory, combined with experimental verification of the hypothesis and any necessary modification of the theory
What is the scientific method?
Matter that can be separated into its components by physical means.
What is a mixture?
This is the SI Unit for temperature.
What is Kelvin (K)?
