- The density or gasoline is 7.30 102 kg/m3 at 0C. Its average coefficient of volume expansion is 9.60 104(C)1 and note that 1.00 gal = 0.003 80 m3. (a) Calculate the mass of 10.0 gal of gas at 0C. (b) If 1.000 m3 of gasoline at 0C is warmed by 20.0C, calculate its new volume. (c) Using the answer to part (b), calculate the density of gasoline at 20.0C. (d) Calculate the mass of 10.0 gal of gas at 20.0C. (e) How many extra kilograms of gasoline would you get if you bought 10.0 gal of gasoline at 0C rather than at 20.0C from a pump that is not temperature compensated?Please answer the question in the pictureSuppose that the Earth wore a snug steel belt around its equator (r = 6378 km). If everyone on Earth breathed on this steel belt simultaneously so that the belt's temperature increased by 2°C, how high off of the Earth would the belt be lifted? Hint: the coefficient of linear expansion of steel is 0.000012 Convert your answer from km to feet. 1 km = 1000 m 1 meter = 3.28 feet

A) 146 liters B) 166 liters C) 186 liters D) 196 litersGlobal warming will result in sea level rise. Assume that i) 2/3 or the earth's surface is oceans with average depth of the oceans is 3000m ii) that sea level rise will not result in the increase in the surface area of the oceans iii) that all of the oceans' water is at a the same temperature of 20°C and has (volume) coefficient of thermal expansion of ß = 2 x 10-4 K-¹. How much will the sea level rise for a 3°C rise in the average water temperature? (You should neglects the effects from the ice caps melting due to this temperature rises.)
