With the tank at least partially filled so there is some water above the pressure gauge, change fluid density to gasoline: 700kg/m3. Record pressure gauge reading kPa. Change fluid density to close to honey: 1400kg/m3. Record pressure gauge reading kPa. Does the pressure double when the density of the liquid doubles

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)
