Part 1 Flashcards
Study of matter
chemistry - is the branch of science that deals with the properties, composition, and structure of elements and compounds, how they can change, and the energy that is released or absorbed when they change.
Anything that occupies space and has mass
Matter - is a substance made up of various types of particles that occupies physical space and has inertia.
Refers to the amount of matter
present in the material
MASS - is the quantity of matter in a physical body. It is also a measure of the body’s inertia, the resistance to acceleration when a net force is applied.
Mass multiplied
to gravity
Weight:
particles are packed tightly together. have definite shape and mass and volume
solid - is one of the four fundamental states of matter. The molecules in a solid are closely packed together and contain the least amount of kinetic energy.
particles are more loosely packed than in a solid. are able to flow in around each other
liquid - is the only state with a definite volume but no fixed shape.
particles have a great deal of of space between them, have high kinetic energy and has no definite shape and or volume
GAS - a fluid (such as air) that has neither independent shape nor volume but tends to expand indefinitely.
colorless fluid part of blood lymph
PLASMA - amber colored protein rich liquid that separates out when blood coagulates
simplest form of matter. one kind of material or atom
ELEMENT - is a substance that cannot be broken down into simpler components by any non-nuclear chemical reaction. An element is uniquely determined by the number of protons in the nuclei of its atoms.
two of more elements united chemically in definite proportion
COMPOUND - something formed by a union of elements or parts especially : a distinct substance formed by chemical union of two or more ingredients in definite proportion by weight a new antibiotic compound.
two or more substances that are not chemically combined
MIXTURE - a mixture is a material made up of two or more different chemical substances which are not chemically bonded.
TWO TYPES OF MIXTURE
HOMEGENOUS MIXTURE - components mix with each other and its composition is uniform throughout the solution
HETEROGENOUS MIXTURE - not mix with each other and it is uniform throughout different components are observe
composed of solute and solvent where solute is soluble
SOLUTION - a special type of homogeneous mixture composed of two or more substances.
finely divided
solid materials distributed in a
liquid where solid is insoluble
SUSPENSION - is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation.
particles of solute not
broken down to the size of the
molecules but are small
enough to remain suspended
COLLOID - d is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance.
