Answer:

Q = 231.6 J

Explanation:

Given that,

Mass, m = 3 g

The temperature rises from 20°C to 220°C.

We know that, the specific heat of copper is, c = 0.386 J/g K

We know that the energy transferred in heating of copper is given by :

[tex]Q=mc\Delta T\\\\Q=3\times 0.386\times (220-20)\\\\Q=231.6\ J[/tex]

So, the required energy is equal to 231.6 J.
