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.
Life in the Intertidal Zone. The intertidal zone -- the area between high and low tides -- is a harsh and unforgiving habitat, subject to the rigors of both the sea and the land.It has four distinct physical subdivisions based on the amount of exposure each gets -- the spray zone, and the high, middle, and lower intertidal zones.ife in the Intertidal Zone.
