Global warming will produce rising sea levels partly due to melting ice caps and partly due to the expansion of water as average ocean temperatures rise. To get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00 C. Assume the column is not free to expand sideways. As a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to the surface can expand sideways onto land, and only to a limited degree. As another approximation, neglect the fact that ocean wan-ling is not uniform with depth.

As part of a biology field trip, you have taken an equal-arm balance (Fig. P1. 14) to the beach. Your plan was to measure the masses of various mollusks, but you forgot to bring along your set of Standard gram masses. You notice that the beach is full of pebbles. Although there are variations in color, texture, and shape, you wonder whether you can somehow use the pebbles as a Standard mass set. Develop a procedure for assembling a Standard mass set from the pebbles on the beach. Describe your procedure step by step so that someone else could follow it.
