Here you have to keep in mind the equation to determine the amount of heat (Q) that one body of mass <em>m </em>can take. The equation is : [tex] Q=mc\Delta T [\tex]
where <em>m</em> is the mass, <em>c</em> is the specific heat and [tex] \Delta T [\tex] the temperature variation. This way: Q=1400kg*3.52J/gºC*(28.5-27.45) ºC=1400000 g*3.52 J/gºC * (28.5-27.45)ºC=5174400J=5174.4 kJ=5.17 MJ.
