# 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,

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
