Answer:
Copper
Explanations:
The formula for calculating the amount of heat gained by the object is expressed as:
[tex]Q=mc\triangle t[/tex]
where:
• m is the mass = 10.4gram
,
• Q = 40.0J
,
• △t = 50 - 40 = 10 degree celsius
Substitute
[tex]\begin{gathered} c=\frac{Q}{m\triangle t} \\ c=\frac{40}{10.4(10)} \\ c=\frac{40}{104} \\ c=0.3846J\text{/}g^0C \\ \end{gathered}[/tex]
This shows that the identity of the metal is copper
