Answer
The required heat is $3.07\times 10^6~J$
Work Step by Step
We can find the heat required:
$Q = m~c_i~\Delta T+m~L+m~c_w~\Delta T+m~V+m~c_s~\Delta T$
$Q = m~(c_i~\Delta T+L+c_w~\Delta T+V+c_s~\Delta T)$
$Q = (1.0~kg)[(2100~J/kg~C^{\circ})(20.0~C^{\circ})+(333\times 10^3~J/kg)+(4186~J/kg~C^{\circ})(100.0~C^{\circ})+(2260\times 10^3~J/kg)+(2010~J/kg~C^{\circ})(10.0~C^{\circ})]$
$Q = 3.07\times 10^6~J$
The required heat is $3.07\times 10^6~J$
