A stock-car race exhibits mostly kinetic energy. The cars moving at high speeds have lots of kinetic energy, but the fuel inside of them has chemical potential energy, allowing them to convert it into more kinetic energy and keep moving. Atlantic cod (Gadus morhua) is a demersal fish species that inhabits the North Atlantic Ocean and adjacent marine areas including the Baltic Sea and the Gulf of St. Lawrence. Reduced exchanges of water with the North Sea and human derived inputs promoting eutrophication may explain the low oxygen levels observed in the Baltic Sea.

According to Grahams law, the molecules of a gas are in rapid motion and the molecules themselves are small. The average distance between the molecules of a gas is large compared to the size of the molecules. The kinetics of manganese oxidation by O 2 in homogeneous solution need to be understood in a more fundamental and quantitative way.
