The amount of heat required for changing the temperature of copper has been 606 J. Thus, option B is correct.
Specific heat has been defined as the amount of heat required to raise the temperature of 1 gram of substance by 1 degree Celsius.
The heat required to raise the temperature has been expressed as:
![\rm Heat=mass\;\times\;specific\;heat\;\times\;Change\;in\;temperature](https://tex.z-dn.net/?f=%5Crm%20Heat%3Dmass%5C%3B%5Ctimes%5C%3Bspecific%5C%3Bheat%5C%3B%5Ctimes%5C%3BChange%5C%3Bin%5C%3Btemperature)
<h3>Computation for the heat energy required</h3>
The given specific heat of copper has been ![\rm 0.385\;J/g^\circ C](https://tex.z-dn.net/?f=%5Crm%200.385%5C%3BJ%2Fg%5E%5Ccirc%20C)
The mass of copper has been, ![\rm 35\;g](https://tex.z-dn.net/?f=%5Crm%2035%5C%3Bg)
The initial temperature of copper has been, ![\rm 20^\circ C](https://tex.z-dn.net/?f=%5Crm%2020%5E%5Ccirc%20C)
The final temperature of copper has been, ![\rm 65^\circ C](https://tex.z-dn.net/?f=%5Crm%2065%5E%5Ccirc%20C)
The change in temperature has been, ![\Delta T](https://tex.z-dn.net/?f=%5CDelta%20T)
![\Delta T=\text{Final\;temperature-Initial\;temperature}\\\Delta T =65^\circ \text C-20^\circ \text C\\\Delta T=45^\circ \text C](https://tex.z-dn.net/?f=%5CDelta%20T%3D%5Ctext%7BFinal%5C%3Btemperature-Initial%5C%3Btemperature%7D%5C%5C%5CDelta%20T%20%3D65%5E%5Ccirc%20%5Ctext%20C-20%5E%5Ccirc%20%5Ctext%20C%5C%5C%5CDelta%20T%3D45%5E%5Ccirc%20%5Ctext%20C)
Substituting the values for the heat required as:
![\rm Heat=35\;g\;\times\;0.385\;J/g^\circ C\;\times\;45^\circ C\\Heat=606\;J](https://tex.z-dn.net/?f=%5Crm%20Heat%3D35%5C%3Bg%5C%3B%5Ctimes%5C%3B0.385%5C%3BJ%2Fg%5E%5Ccirc%20C%5C%3B%5Ctimes%5C%3B45%5E%5Ccirc%20C%5C%5CHeat%3D606%5C%3BJ)
The amount of heat required for changing the temperature of copper has been 606 J. Thus, option B is correct.
