Answer:
Metal is copper.
Explanation:
Mass of a metal, m = 54 g
Heat energy required, Q = 773 J
The temperature changes from 63.0 °C to 100.0 °C.
We need to identify the metal. Heat required to raise the temperature is given by :
[tex]Q=mc\Delta T[/tex]
c is specific heat of the metal
We can identify the metal by finding its specific heat.
[tex]c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{773}{54\times (100-63)}\\\\=0.386\ J/g^{\circ} C[/tex]
The metal is copper. Its specific heat is [tex]0.386\ J/g^{\circ} C[/tex].
