![m_1\times c_1\times (T_{final}-T_1)=-[m_2\times c_2\times (T_{final}-T_2)]](/tpl/images/0640/3386/09236.png)
    .................(1)
= mass of gold = 1.3 kg
= mass of copper = 2.1 kg
= final temperature = ?
= temperature of gold= 300 K
= temperature of copper = 400 K
= specific heat of gold = 
= specific heat of copper =
