`(a)` Calculate the energy needed  to raise the temperature of `10.0g` of iron from `25^(@)C` to `500^(@)C` if specific heat capacity  of iron  if `0.45J( .^(@)C)^(-1)g^(-1)`  `(b)`  What mass of gold `(` of specific heat capacity `0.13J ( .^(@)C)^(-1)g^(-1)` can be heated can be heated through the same temperature  difference when supplied with the same amount of energy as in `(a)` ?
