The difference between Lung Capacity and Vital Capacity is that the former is the total volume of air in the lungs where as latter is the maximum volume of air that can be inhaled and exhaled during forced breathing.
The advantages of high specific heat capacity of water are (a) Water has the highest specific heat capacity. It therefore takes a long time to heat and long time to cool. The following uses/ effects are due to the high specific heat capacity of water and etc.
