Answer:Water Only
Explanation:
Given
vessel is insulated therefore no heat can be added or removed i.e. heat exchange is zero
If hot water at is mixed with cold water at then at equilibrium vessel contains only water and final temperature of water will be between and
Heat released by hot water is equal to heat gain by cold water .
If you're only melting ice ... turning solid ice at 0°C into liquid water at 0°C ...
then you only need to know t<span>he latent heat of fusion for water</span>.
That's exactly what it means ... the amount of energy involved when a gram
of H₂O changes in either direction between liquid and solid, with no change
in temperature.
