Name: PHS 212A - Spring EXAM II - Heat, Temperature, & Thermodynam 4. A glass jar with an aluminum lid is stuck shut. You decide to search the internet for a way to get it unstuck, and someone says hold the lid+jar under hot water. Based on their coefficients of thermal expansion, which should expand more in the hot water? (a) The aluminum lid (b) The glass jar (c) They should expand the exact same amount Global Sea Level change (m) 1807-2010 0.25 5 1971-2000 Avg: 0.12m 0.1 0.05 1900-1950 Avg Global Average Sea Level (meters 0.05 BODE 1950 2000 2050 -0.1 0.15 -0.2 -0.25 Data from Global Sea Level Reconstruction 1807-2010 by Jevrejeva et al., GPC 2014 available at psmsi.org 5. This is a graph of historical sea level, in meters, from the year 1807 until 2010. You can see that between the year 1860 until 2010, the sea level rose steadily by about AL= 0.3 m. If this sea level rise AL was entirely due to thermal expansion of warming sea water, calculate the change in sea water temperature AT, in Celsius, that could explain it. Note: the average depth of the ocean L=3650m and the average coefficient of linear expansion for seawater is a = 200 x 10-61/C. (a) 0.22 C (b) 0.41 .C (c) 2.43 .C (d) 5.23 .C
