how much heat would be required to warm the earth's oceans by 1 degree celcius if the volume of the earths oceans is 137x100000000km3 and the density of the seawater is 1.03g/cm3

Answer 1

mass H2O = volume x density
heat required = mass H2O x specific heat H2O x 1

Note: You will need to change volume from km^3 to cc or a unit that agrees with the specific heat units you use.
