Gibbs himself considered the following problem that arises if the ideal gas entropy is not extensive. Two identical containers of an ideal gas sit side-by-side. There is a certain amount of entropy S associated with each container of gas, and this depends on the volume of each container.
The intertidal zone is the area of the ocean between the high tide and low tide lines, usually on the beach at the water's edge. If you think of the line created at high tide as the upper limit and the line created at low tide as the lower limit, the intertidal zone is everything between those lines.
It includes the inner sublittoral zone to adepth of 50 m, the deepest zone for attached plants and algae,and the outer sublittoral zone from the inner zone out to a depthof 200 m or the shelf break.Suboceanic:i. The bathyl zone is from a depth of 200 to 4000 m.
