NYU General Chemistry Chapter 1
Chemistry - answer study of matter, its properties, and electron behavior
Matter - answer anything that has mass and occupies space
Composition - answer types and amounts of simpler substances that make up a sample
of matter
Substance - answer matter that has definite, fixed composition and distinct properties;
has a certain quality
Mixture - answer2 or more substances physically mingling
Property - answer observable characteristic
Physical Property - answer can be measure/observed without changing its identity
(includes density, melting/boiling point)
Chemical Property - answer can only be observed during a chemical change
Macroscopic Properties - answercan be measured directly
Submicroscopic Properties - answercannot be measure directly
Kinetic Energy - answerenergy due to motion
Potential Energy - answerenergy due to position
Mass - answermeasure of quantity of matter in an object
Weight - answerforce that gravity exerts on an object
Heat - answertransfer of thermal energy from warmer object to cooler object
Temperature - answermeasure of amount of thermal energy an object has
Extensive Properties - answerdependent on amount of substance (ex. mass, volume,
energy)
Intensive Properties - answerindependent of amount of substance (ex. density,
temperature)
