The specific heat of iron metal is 0.450 ${\rm{J/g}} \cdot {\rm{K}}$ .

How many ${\rm J}$ of heat are necessary to raise the temperature of a 1.25 $-\,kg$ block of iron from 23.0 $^\circ C$ to 89.5 $^\circ C$ ?

1.25*1000*0.450*(89.5-23)

DO not rely on my answer. I am not from physics. I think its class 12 formula H=ms(t2-t1)
