identify a metal‚ each with varying amounts of accuracy. In order to test some of these methods‚ thermal expansion‚ density‚ and specific heat were used to identify two small metal rods. The overall purpose of this experiment was to identify an unknown metal using the three previously stated properties. This means that the percent error should be relatively low‚ meaning that there would be little difference between the values measured in our experiment and the true values of the metal. Density

Prokaryotes: Bacteria Most of us have been conditioned to think of bacteria as invisible‚ potentially harmful little creatures. Actually‚ relatively few species of bacteria cause disease in humans‚ animals‚ plants‚ or any other organisms.
