Answer:
![Q=1,698.7J](https://tex.z-dn.net/?f=Q%3D1%2C698.7J)
Explanation:
Hello!
In this case, since the calculation of the required energy is performed via the following equation:
![Q=mC(T_f-T_i)](https://tex.z-dn.net/?f=Q%3DmC%28T_f-T_i%29)
Thus, since the mass is 14 g, specific heat is 4.184 J(g*°C) and the temperatures are 47 °C and 18 °C respectively, the resulting energy is:
![Q=14g*4.184\frac{J}{g\°C}(47°C-18°C)\\\\Q=1,698.7J](https://tex.z-dn.net/?f=Q%3D14g%2A4.184%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%2847%C2%B0C-18%C2%B0C%29%5C%5C%5C%5CQ%3D1%2C698.7J)
Best regards!
