Question

Help/quick answer. I understand how to solve i just want to see if i am correct on my answer.

Answer 1

Copper

Explanations:

The formula for calculating the amount of heat gained by the object is expressed as:

`Q=mc\triangle t`

where:

• m is the mass = 10.4gram

,

• Q = 40.0J

,

• △t = 50 - 40 = 10 degree celsius

Substitute

`\begin{gathered} c=(Q)/(m\triangle t) \\ c=(40)/(10.4(10)) \\ c=(40)/(104) \\ c=0.3846J\text{/}g^0C \\ \end{gathered}`

This shows that the identity of the metal is copper
