Inorganic material - introduction
Inorganic compounds don't ususally contain carbon, except in very simple
molecules. Examples of inorganic compounds are carbon dioxide, CO2 and
water, H2O. Living organisms are between about 60 percent - 90 percent
Chemical reactions take place in a watery medium as water is an important
Water has a high heat capacity. It can absorb heat well without getting
Water molecules are cohesive - they tend to stick together. This is
important in capillary action in xylem and for the surface tension of
bodies of water.
Now let's have a look at two other examples: minerals and carbon dioxide.
Water molecule (hydrogen atoms = white, oxygen = red).
