... down more quickly.) THEORY:- When the copper particles of the calorimeter are heated by the Bunsen burner, kinetic energy is transferred very easily to them and they violently vibrate on their axis. This is an example of conduction. A fairly still atom can pick u[p vibration from a hot atom because they are joint together by bonds. The copper conducts heat very well, and the heat is transferred from atom to atom. The touching liquid particles get energy and violently move around faster. Convection is also occurring during this experiment through liquids and gases. Convection currents will be in the water in this experiment. The warm particles rise to replace the cold, which sink, and the particles expand, become less dense, and begin to rise up, carrying extra heat with it. Radiation is totally different from conduction and convection because it doesn't need particles. Every object sends out infrared radiation and hot objects ...
