States Of Matter

Front 1

solid

Back 1

firm and stable in shape; not liquid or fluid.

Front 2

liquid

Back 2

having a consistency like that of water or oil, flowing freely but of constant volume

Front 3

gas

Back 3

an airlike fluid substance which expands freely to fill any space available, irrespective of its quantity

Front 4

viscosity

Back 4

the state of being thick, sticky, and semifluid in consistency, due to internal friction

Front 5

surface tension

Back 5

the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area

Front 6

physical property

Back 6

A physical property is any property that is measurable, whose value describes a state of a physical system

Front 7

chemical property

Back 7

a property or characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed

Front 8

phase change

Back 8

phases of matter definition. The states in which matter can exist as a solid, liquid, or gas

Front 9

physical change

Back 9

A physical change is a change in which no new substances are formed

Front 10

chemical change

Back 10

Chemical change is any change that results in the formation of newchemical substances

Front 11

precipitate

Back 11

cause a substance to be deposited in solid form from a solution

Front 12

atom

Back 12

the basic unit of a chemical element

Front 13

element

Back 13

a part or aspect of something abstract, especially one that is essential or characteristic

Front 14

compound

Back 14

a thing that is composed of two or more separate elements; a mixture

Front 15

mixture

Back 15

a substance made by mixing other substances together

Front 16

melting

Back 16

make or become liquefied by heat

Front 17

evaporation

Back 17

Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure

Front 18

freezing

Back 18

freezing point definition. The temperature at which a liquid changes into a solid

Front 19

boiling

Back 19

the action of bringing a liquid to the temperature at which it bubbles and turns to vapor

Front 20

condesation

Back 20

water that collects as droplets on a cold surface when humid air is in contact with it

Front 21

sublimation

Back 21

Sublimation is a chemical process where a solid turns into a gas without going through a liquid stage

Front 22

endothermic reaction

Back 22

The term endothermic process describes a process or reaction in which the system absorbs energy from its surroundings

Front 23

exothermic reaction

Back 23

An exothermic reaction is a chemical reaction that releases energy by light or heat
