Calculate the specific heat of a metallic element if 31j of energy are needed to raise the temperature of a 50.0g sample from 25.0c to 50.0c?

Specific heat of a metal is the amount of energy required to heat one gram of the metal by 1 degree celsius.   
Heat energy = (mass of substance)(specific heat)(change in temperature)
 Mass of substance = 50 g
 Heat energy =31 Joules
 Change in temperature = 25 degree celsius. 
 Hence, specific heat = (31)/(50*25) = 0.0248 J/g deg Celsius

The answers is a nuclear changes

Wow that a lot of text for my tiny so i no wanna answer
