Given data:

Mass of copper is,


m_c=1\text{ kg}

Initial temperature of copper is,


T_i=330^oC

Final temperature of copper is,


T_f=3300^oC

Melting point of copper is,


T_m=1085^oC

Specific heat capacity of copper is,


c=389\text{ J/kg}\cdot^oC

Latent heat of fusion of copper is,


L_f=206*10^3\text{ J/kg}

Boiling point of copper is,


T_b=2562^oC

Latent heat of vaporization of copper is,


\begin{gathered} L_v=322.1\text{ }*10^3\text{ J/mol} \\ L_v=5069.85\text{ }*10^3\text{ J/kg} \end{gathered}

Now,

Formula of heat needed to change the temperature of copper,


\Delta T=1085^oC-330^oC=755^oC

Formula:


Q=mc\Delta T

Substitute known values in above equation,


\begin{gathered} Q_1=1\text{ kg}*389\text{ J/kg}\cdot^oC*755^oC \\ Q_1=293695\text{ J} \end{gathered}

Formula for heat needed to melt copper is,


Q=mL_f

Substitute known values in above equation,


\begin{gathered} Q_2=1\text{ kg}**206*10^3\text{ J/kg} \\ Q_2=206000\text{ J} \end{gathered}

Formula of heat needed to raise temperature of copper,


\Delta T=2562^oC-1085^oC=1477^oC

Formula:


Q=mc\Delta T

Substitute known values in above equation,


\begin{gathered} Q_3=1\text{ kg}*389\text{ J/kg}\cdot^oC*^{}1477^oC \\ Q_3=574553\text{ J} \end{gathered}

Now, formula of heat needed to vaporization of copper is as follows:


Q_4=mL_v

Substitiute known values in above equation,


\begin{gathered} Q_4=1\text{ kg}*5069.85*10^3\text{ J/kg} \\ Q_4=5069850\text{ J} \end{gathered}

Formula of heat needed to change the temperature of copper,


\Delta T=^{}3300^oC-2562^oC=738^oC


Q_5=mc\Delta T

Substitute known values in above equation,


\begin{gathered} Q_5=1\text{ kg}*389\text{ J/kg}\cdot^oC*738^oC \\ Q_5=287082\text{ J} \end{gathered}

Above diagram is the phase diagram of copper.
