Bildnummer 11827345
| Robert Boyle. Engraving of Robert Boyle (1627-91),the British chemist who established chemistry as a separate science. His work stressed the need for experiment,precision and accurate observation. Boyle rejected the theory that 4 elements (fire,air,water and earth) were the basic constituents of the Universe. Boyle postulated that there were a large number of 'elements' which could not be broken down into simpler chemicals. He formulated Boyle's law,which states that for a gas at a constant temperature the product of its pressure and volume is a constant. He devised analytical tests including the use of vegetable dyes as acid- base indicators and flame tests to detect metals | |
