(a)Calculate the energy needed to raise the temperature of 10.0 g of iron from `25^(@)`C to `250^(@)C` if specific heat capacity of iron is 0.45J `.^(@)C^(-1)g^(-1)`.
(b) What mass of copper (specific heat capacity = 0.385 J `.^(@)C^(-1)g^(-1)`) can be heated through the same temperature difference when supplied with the same amount of energy as above.

Explanation

To solve the problem step by step, we will break it down into two parts as per the question.

### Part (a): Calculate the energy needed to raise the temperature of 10.0 g of iron from 25°C to 250°C.

1. **Identify the given values:**
- Mass of iron (m) = 10.0 g
- Specific heat capacity of iron (s) = 0.45 J/(°C·g)
- Initial temperature (T_initial) = 25°C
