EDM 321 MID MIXTURES

Made up of two or more substances or materials that are put together by physical means

No new substances and or materials are formed because mixing substances and materialstogether does not change their physical properties

One or more phases of matter are combined in a mixture and one or more phases can be observed.

3 basic characteristics of mixtures:

Mixtures can be classified as

well-mixed mixtures,appear single-phased. - Particle size is too small to be seen by naked eyes

unevenly-mixed mixtures- particles of one or more components can still be differentiated from the rest of the mixture by the unaided eye.- Two or more phases of matter can be observed.

Changes in Matter

- Solid to Liquid

Liquid to Solid

Liquid to Gas

- Gas to Liquid

- Solid to Gas

change in the form/ appearance of a substance, but its chemical composition remains the same.no new substance is formed,change is often reversible.

Changes in matter that results in formation of one or more substances. The new material has diff composition compared to original material
