It is a popping resonating sound generated by a lean condition on deceleration. When you suddenly close the throttle, the incoming air is choked off and the closed throttle also causes the bike to return to idle on the very lean idle circuit.
The reactivity series of metals was deduced by performing several experiments in the lab which enabled scientists to arrange metals according to their reactivity with dilute acid, oxygen (air), and water.xides of iron and copper are insoluble. Metals that are less reactive than copper like silver, gold and platinum do not react with oxygen. Note: When aluminum reacts with oxygen, a layer of aluminum oxide adheres and covers the aluminum.
Silver has the highest conductivity of any metals: 63 x 10 6 S/m. Water conductivity. Pure water is not a good conductor of electricity. Ordinary distilled water in equilibrium with carbon dioxide of the air has a conductivity of about 10 x 10 -6 W -1 *m -1 (20 dS/m).Because the electrical current is transported by the ions in solution, the conductivity increases as the concentration of ions increases.Thus conductivity increases as water dissolved ionic species. Ultra pure water 5.5 Â· 10 -6 S/m. Drinking water 0.005 â 0.05 S/m.ilver has the highest conductivity of any metals: 63 x 10 6 S/m. Water conductivity. Pure water is not a good conductor of electricity. Ordinary distilled water in equilibrium with carbon dioxide of the air has a conductivity of about 10 x 10 -6 W -1 *m -1 (20 dS/m).
