Calculate the energy needed to raise the temperature of 10 g of iron from 25 degree Celsius to 500 degree Celsius if specific heat capacity of iron is 0.45 Jg -1degree Celsius -1.

Dear Student,

Please find below the solution to the asked query:

Difference in temperature ΔT = (500-25) = 475oC
​Specific heat =  0.45J/goC  [given]
mass =10g [given]
Q = mass × specific heat × ​ΔT                     [where Q= energy required
                                                                                   ​ΔT = difference in temperature]

Q = 10g × 0.45J/go×475oC
  = 2137.5 J
