Document Summary
Matter is all the material in the universe that has a mass and occupies space, whether solid, liquid or gaseous. Matter may be transformed from one state to another but cannot be created or destroyed. Element: is a fundamental type of matter, a chemical substance with a given set of properties. A polar molecule with a partial negative charge due to oxygen"s increased electronegativity that attracts electrons more than the hydrogen atom leaving the molecule with a slight positive dipole and a slight negative dipole. Water remains a liquid from 0 to 100 degrees, which allows biological processes to occur at a wide range of environmental conditions. Water exhibits strong cohesion which allows the transport of chemicals, such as nutrients and waster, in plants and animals and in the physical environment. Water has a high heat capacity, which means that water can absorb large amount of heat with a minimal change in temperature.
