Answer:

168277.2 J

Explanation:

m = Mass of water = 600 g

c = Specific heat of water = 4.186 J/g°C

[tex]\Delta T[/tex] = Change in temperature of water = [tex]89-22=67^{\circ}\text{C}[/tex]

We know that the amount of heat lost = amount of heat gained

[tex]Q=mc\Delta T\\\Rightarrow Q=600\times 4.186\times 67\\\Rightarrow Q=168277.2\ \text{J}[/tex]

Heat lost by the iron bar is 168277.2 J.
