Chemistry, The Molecular Nature of Matter and Change Ch. 1
Questions and Answers
chemistry - correct answersthe study of matter and its properties, the changes that matter undergoes
and the energy associated with those changes
matter - correct answersthe "stuff" of the universe: air, glass, planets, students
Anything that has Mass and Volume
composition - correct answersthe types and amounts of simpler substances that make it up ...
substance - correct answersa type of matter that has a defined, fixed composition
state of matter - correct answersmain three physical forms
solid - correct answersThis state has a fixed shape that does not conform to the container's shape.
Solids are NOT defined by rigidity or hardness.
Particles lie next to each other in a regular, three-dimensional array.
liquid - correct answersThis state has a varying shape that conform to the container shape, but only to
the extent of the liquid's volume. A liquid HAS an upper surface.
Particles lie close together but move randomly around each other.
gas - correct answersThis state has a varying shape that conforms to the container shape, but it fills the
entire container and thus, DOES NOT have a surface.
Particles have large distances between them and move randomly throughout the container.
, property - correct answersThe characteristics that give each substance its unique identity.
physical property - correct answersCharacterisitcs a substance shows BY ITSELF. without changing into or
interacting with another substance.
physical change - correct answersOccurs when a substance alters its physical properties, NOT its
composition.
chemical property - correct answersCharacteristics a substance shows as it changes into or interacts with
another substance (or substances)
chemical change (chemical reaction) - correct answersOccurs when a substance (or substances) is
converted into a different substance (or substances)
energy - correct answersThe capacity to do work, to move matter.
potential energy - correct answersThe energy an object has as a result of its position relative to other
objects or because of its composition.
kinetic energy - correct answersThe energy an object has because of its motion.
combustion - correct answersThe process of burning in air, often with release of heat and light.
scientific method - correct answersA process of creative thinking and testing aimed at objective,
verifiable discoveries of the causes of natural events.
observation - correct answersA fact obtained with the senses, often with the aid of instruments.
Quantitative observations provide data that can be compared.
data - correct answersPieces of quantitative information obtained by observation.
