A6.50-g sample of copper metal at 25.0°c is heated by the addition of 84.0 j of energy. the final temperature of the copper is °c. the specific heat capacity of liquid water is 0.38 j/g-k.

Final temperature of the copper is 59 degrees Celsius

Explanation:

It is given that,

Mass of the sample of copper metal, m = 6.5 g

Initial temperature of the metal,

Heat generated, Q = 84 J

The specific heat capacity of liquid water is 0.38 J/g-K

Let is the final temperature of the copper. It can be calculated using the definition of specific heat of any substance. It is given by :

or

So, the final temperature of the copper is 59 degrees Celsius. Hence, this is the required solution.
