The ocean’s average temperature has risen by approx 0.375°C over the century. Use this value to estimate by how much the ocean water might have expanded in items of percentage increase. This is what i started doing but I do not think this is right. Coefficient of Cubical Thermal Expansion (Y)= change in volume (dv)/ Initial volume (v) * change in temp (dt) Coefficient of volume expansion of water= 207*10^-6 per deg C Linear coefficient = 1/3 cubical coefficient =1/3*207*10^-6 = 6.9*10^-6% But i am not getting the right answer I do not think. Can you please help me?
