9 In the lab, a student places a 5 kg container of water on a hot plate. The heating of the water is constant. The student records the temperature and graphs it as a function
of time on the graph below.
Which point on the above graph has the lowest entropy level ?

Global warming will produce rising sea levels partly due to melting ice caps but also 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 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
