Прочитайте и письменно переведите текст: petroleum petroleum is a complex mixture of hydrocarbons. it contains small amounts of oxygen, nitrogen, and sulphur compounds, and traces of metal salts. hundreds of compounds of varying composition, molecular weight, and structure have been identified. their properties are extremely varied: some boil below room temperature, some cannot be distilled without decomposition; all are combustible. many special products come from petroleum: lubricants, waxes, solvents, asphalts for roads, medicinal oils, and numberless chemical derivatives. but the tremendous growth of the petroleum industry has been based on demand for fuels: gasoline, diesel oil, house heating oils for industrial furnaces and steam and power generation. составьте словарь профессиональных терминов (10 слов и выражений)
