Document Summary

Biology & medicine: biochemistry, nucleobase (adenine(a), thymine(t), guanine(g), cytosine(c), deoxyribonucleic acid (dna, cisplatin: platinum-containing anti-cancer drug. Space: hydrogen gas (h2, we know what atoms and molecules are present in distant objects because of the light emitted and absorbed by them. Physical state & chemical constitution: by its physical state as solid, liquid or gas, by its chemical composition as element compound or mixture. Elements, compounds & mixtures: millions of substances have been characterized by chemists including pure substances and mixtures. Types of physical properties: intensive properties: independent od the amount of the substance that is present, density, boiling point, color, etc, extensive properties: depend upon the amount of the substance present, mass, volume, energy, etc. Types of matter changes: physical changes: changes in matter that do not change the composition of a substance, a physical change in the form of matter, but not in its chemical identity.
