Intro To Matter Flashcards
Matter
Matter is anything that has mass or takes up space.
Chemistry
Chemistry is the study of matter and how matter changes.
Substance
Substance is a single kind of matter that is pure,meaning it has a specific makeup, or composition.
Physical property
Physical property is a characteristic of a substance that can be observed without changing it into another substance.
Chemical property
Chemical property is a characteristic of a substance that describes its ability to change into different substances.
Physical Change
A physical change alters the form or appearance of matter but does not turn any substance in the matter into a different substance.
Chemical Change
A change in matter that produces one or more new substances is a chemical change, or chemical reaction
Law of Conservation of Mass
The fact that matter is not created or destroyed in any chemical or physical change is called The Law of Conservation of Mass.
Temperature
Temperature is a measure of how hot or clod something is.
Chemical Energy
The energy stored in the chemical bonds between atoms is a form of energy called Chemical Energy.
Thermal Energy
Thermal energy is the total energy of the motion of all the particles in an object.
Endothermic Change
The melting of ice is a endothermic change, a change in which energy is absorbed.
Exothermic Change
An exothermic change releases energy.
