10 kg of molten lead at its melting point of 320°C and 1.0 kg of ice at 0°c to be a place inside an insulating chamber where they reach a common final temperature. calculate the final temperature and heat lost by the lead in this process.
Latent heat of fusion of
ice, 3.34×10^5jkg-1
lead, 2.45×10^3jkg-1
specific heat capacity of
ice, 1.28×10^3jkg-1k-1
water, 4.2×10^3jkg-1k-1.
