Given,

Mass of water "m=1200g"

Energy "E=13650" calories"=13650\\times 4.2=57330J"

Specific heat of water "c=4.18J\/gK"


Let "\\Delta t" be the change in temprature


As we know, "Q=mc\\Delta t"


"\\Rightarrow 57330=1200\\times4.18\\times \\Delta t\\\\\\Rightarrow\\Delta t =\\dfrac{57330}{5016}"


"\\Rightarrow \\Delta t=11.42K"
