Explanation:
Here, we want to get the number of Joules needed to be added
Mathematically, this is the amount of heat needed which could be calculated by:
where:
m is the mass of the iron which is 1000 g
c is the specific heat capacity which is 0.449
delta T is the temperature change which is the difference between final and initial temperature (250-25 = 225 degrees celsius)
Substituting the values, we have it that:
