Chemistry-Chapter 3.2 States and Properties of Matter

Solids

Have definite shape, definite volume, maximum force of attraction between particles, particles are closely packed, cannot be composed, kinetic energy of particles is minimum, particles cannot move but only fibrate at their fixed position, high density, and cannot flow

Liquids

Indefinite Shape, Definite Volume, has less fine of attraction between particles compared to a solid, particles are loosely packed compared to a solid, particles can move past one another, lower density than a solid, flows

Gases

Indefinite Shape, Indefinite Volume, Negligible line of attraction between particles, compressible, kinetic energy of particles in maximum, particles more freely, lowest density , flows

It is total disorder; much empty space; particles have freedom of motion; particles fall apart

What is the particle arrangement of gas?

Disorder; particles are free to move past one another; particles are close together

What is the particle arrangement of liquid?

Ordered arrangement; particles are in essentially fixed positions; particles tightly packed

What is the particle arrangement of Solids?

A vapor is the gas phase of a substance that would be a solid or liquid at room temperature, while a gas is something that exist in Gases form naturally at room temp

What is the difference between a gas and a vapor?

physical properties

can be observed without changing the composition

Chemical Properties

Ability of a substance to react with or changing into other substances

Intensive property

Independent of the amount of substances (density, color, odor)

Extensive Property

Dependent on the amount of substances(weight, size volume)

Physical Changes

changes form without changing composition

Phase changing(melting, boiling) and cutting, bending

What are some examples of physical change?

Chemical Changes

process that turns substances into new substances, new substances usually have different properties from the original ones

Rusting, turmising, decomposed, etc.

What are some examples of Chemical Changes?

iron rusts when exposed to oxygen, water doesn't with oxygen in the air

What are some examples of chemical properties?

Density, Melting and Boiling Points, Color, Odor, may be intensive or extensive

What are some examples of Physical properties?

A solid, called a precipitate(formed when liquids are mixed), color change, a gas is produced, temperature change

What are 4 evidences of a chemical reaction?
