Organic Chemistry
Is the scientific study of mater and the physical and chemical changes of matter
Chemistry
when water freezes it becomes ice-its still water , but now its a solid instead of a liquid
Physical Change

Definite weight and indefinite volume and shape
Gas
change in a substance that creates a new substance with chemical characteristics different from those of the original
chemical change
occurs when hydrogen combines with oxygen to form a new substance - water
chemcial
