Physical Properties of Matter • Any property of matter that can be observed or measured without changing the identity of the matter • Examples temperature color shape taste state/phase density
![Density m a measure of the amount of matter present in a given Density m • a measure of the amount of matter present in a given](https://slidetodoc.com/presentation_image_h/20e098b3639f39c0fed43241f40eee00/image-3.jpg)
Density m • a measure of the amount of matter present in a given volume of a substance • typically expressed in the following units: • grams per cubic centimeter (g/cm 3) for solids • grams per milliliter (g/ml) for liquids D • can change as temperature and pressure change • does not depend on how much of a substance you have (intrinsic property) – in other words, the density of a gold bar would be the same as the density of a gold flake Which do you think is more dense? Why? . V

Physical Changes in Matter • Physical Changes: only the phase changes, the substance does not. • Physical changes usually change the size or shape of the substance. • Examples of physical changes include:

Chemical Properties of Matter Any property of matter that describes a substance based on its ability to change into a new substance • Examples flammability combustibility reactivity with vinegar reactivity with oxygen Iron + Oxygen Iron oxide (rust) 2 Fe + 3 O 2 Fe 2 O 3

Why do you think Bose-Einstein and plasma are not equally distanced from the other three states of matter? Changes in States (Physical Changes) Ionization Disposition Recombination Vaporization (Evaporation/Boiling) Solid Gas Condensation Liquid Melting Plasma Freezing Sublimation Bose-Einstein All changes in state require a change in energy

EXOTHERMIC ENDOTHERMIC Exothermic- the word describes a process that releases energy in the form of heat. Forming a chemical bond releases energy and therefore is an exothermic process. Exothermic reactions usually feel hot because it is giving heat to you. Endothermic - a process or reaction that absorbs energy in the form of heat. Breaking a chemical bond requires energy and therefore is Endothermic reactions usually feel cold because it is taking heat away from you.

Law of Conservation of Matter • Matter cannot be created or destroyed. Either it is changed physically or chemical changes allow for atoms to break and establish new bonds creating different substances with the same molecules.

Mass vs. Weight Mass • a measure of how much matter an object is made of • the force of gravity on an object • does not change, regardless of where something or • equal to the mass of the body times the local acceleration of gravity someone is Why do you think the person’s weight is less on the moon? Mass = 59 kg Weight = 579 N Weight = 96 N http: //www. exploratorium. edu/ronh/weight/index. html
