Question

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 (in m) of a column of water 1.35 km high for a temperature increase of 1.24°C. Note that this calculation is only approximate because ocean warming is not uniform with depth. (Assume the expansion of the column is unconstrained.)

Answer 1

sol The relation between change in length and change in temperature is AL : LIAT The coefficient of volume expansion is r=82 . d= 735 = dioxiöbel = 70x106 or in length of column water is AL = 1-25 (1000) (10 x16 , clayºl Ik 11-718x10 - 0.0117 m.
