Chemistry - (answers)The study of the properties of matter and how matter
changes
Basic Unit in Chemistry - (answers)atom
Types of Chemistry - (answers)Green Chemistry
Sustainable Chemistry
green chemistry - (answers)uses materials and processes that are intended to
prevent or reduce pollution at its source
replacing rare hazardous with more abundant less hazardous
Example of green chemistry - (answers)replacement of mercury fluorescent light
bulbs with efficient mercury free light bulbs
Green Chemistry Solar Fuels - (answers)sunlight is abundant source of energy
plants store solar energy as chemical energy via photosynthesis
artificial photosynthesis - (answers)can be used to generate hydrogen fuel
, 2
H fuel can then be reacted with O to produce heat and electricity
water---->hydrogen + oxygen
sustainable chemistry - (answers)designed to meet the needs of the present
generation without compromising the needs of future generations
Matter - (answers)Anything that has mass and takes up space
mass - (answers)A measure of the amount of matter in an object
weight - (answers)A measure of the gravitational force exerted on the matter of
an object.
Classes of Matter - (answers)Solids, Liquids, Gas
Solid - (answers)Definite shape and volume
vibration
ice, brick, wood,
liquid - (answers)A state of matter that has no definite shape but has a definite
volume.
move in irregular pattern
petrol, vinegar, paint, water
, 3
gas - (answers)A state of matter with no definite shape or volume
freely move continuously- far apart
helium, oxygen, carbon monoxide, hydrogen
melting point - (answers)The temperature at which a solid becomes a liquid
Vaporation - (answers)Liquid to gas
boiling Point - (answers)temp at which liquid escapes and becomes a gas
condensation - (answers)Gas to liquid
freezing - (answers)liquid to solid
occurs at freezing point/same as melting point
Sublimation - (answers)A change directly from the solid to the gaseous state
without becoming liquid
Ex: dry ice
2 categories of matter - (answers)substances and mixtures
, 4
Substance - (answers)A single kind of matter that is pure and has a specific set of
properties.
Substance contains - (answers)Elements and Compounds
Elements - (answers)A molecule composed of one kind of atom; cannot be broken
into simpler units by chemical reactions.
represented by chemical groups:
Cl, H, Mg
Compounds - (answers)2 or more elements chemically combined
many exist as groups of atoms bonded together as molecules
Atoms - (answers)Building blocks of matter
smallest particle in an element
Aristotle - (answers)A Greek Philosopher,
