Here is a diagram to better visualize the problem. My homework question asks to find the temperature at point c. I have already calculated that n=0.41 and that the pressure at point b is 2.01966 atm. You do not need to solve for c, just please tell me how. Okay so I couldn't handle it anymore and I just looked at the answer which happened to be 810J. This make me even more confused.
The annelid worms owe their evolutionary success to segmentation. The coelom becomes divided into a linear series of identical fluid-filled compartments, or segments, that run between the head and the anus. The 8,600 species of annelid worms take their name from the Latin anellus, meaning little ring.
Section 4 â¢ Segmented Worms 747 Circulation Unlike most mollusks, most annelids have a closed circulatory system. Oxygen and nutrients move to various parts of their bodies through their blood vessels. At the same time carbon dioxide and metabolic wastes are removed from the blood and excreted. Some of the vessels at the anterior end, or
