Question

calculate the energy needed to raise the temperature of 10gm of iron from 25°c to 500°c If the specific heat of iron in 0.45J(°c–1)(gm–1) plz answer my question​

Answer 1

formula: E=mc∅

m= 10gm = 0.01kg

c= 0.45j/g c = 450j/kg c

∅= 500-25 = 475 degrees celsius

therefore,

E= 0.01 x 450 x 475

 = 2137.5 J

Hope this helps:)
