Answer
The amount of heat required is $2.45\times 10^5~J$
Work Step by Step
We can find the amount of heat required to raise the temperature by $1.4~ C^{\circ}$:
$Q = m~c~\Delta T$
$Q = (50.0~kg)(3500~J/kg~C^{\circ})(1.4~C^{\circ})$
$Q = 2.45\times 10^5~J$
The amount of heat required is $2.45\times 10^5~J$.
