Chapter 1 Introduction to Matter Flashcards
(27 cards)
Anything that has mass and takes up space
Matter
The study of matter and how matter changes
Chemistry
A single kind of matter that is pure
Substance
A characteristic of a substance that can be observed without changing into another substance
Examples: Color, Texture, Size, States of matter
Physical Property
A characteristic of a substance that describes its ability to change into different substances
Chemical Property
A substance that cannot be broken down into any other substance by chemical or physical means
Element
The basic particle from which all elements are made
Atom
A force of attraction between two atoms
Chemical Bond
A group of two or more atoms held together by chemical bonds
Molecule
A substance made by two or more elements that are chemically combined in a set ratio
Compound
Shows the elements in a compound and the ratio of the atoms
Chemical Formula
Made of two or more substances that are together in the same place but they are not chemically combined
Mixture
Different parts can be easily seen and separated out of the mixture
Heterogeneous Mixture
So evenly mixed that you cannot see or separate the different parts of the mixture
Homogeneous Mixture
A measure of the force of gravity on an object
Weight
The amount of matter in an object which does not change with location even if the force of gravity changes
Mass
A system of measurements based on ten and on established measures of mass, length and time
International System of Units
The amount of space that matter occupies
Volume
A measure of the mass of a material in a given volume
Density
This alters the form or appearance of matter but does not turn any substance in the matter into a different substance
Physical Change
A change in matter that produces one or more new substances
Chemical Change
The fact that matter is not created or destroyed in any chemical or physical change
Law of Conservation of Mass
A measure of how hot or cold something is. It is related to the energy of motion of the particles of matter
Temperature
The total energy of the motion of all of the particles in an object
Thermal Energy
