Cold and high salinity. Hope this helps :)
What are the options tell me from comment of this answer
Heat required : Q = 83500 J = 83.5 kJ
<h3>
Further explanation
</h3>
Given
mass ice = 250 g at 0°C
Required
The heat required
Solution
The heat to change the phase can be formulated :
Q = m.Lf (melting/freezing)
Lf=latent heat of fusion
Input the value :
Q = 250 g x 334 J/g
Q = 83500 J
