Aman would like to study the heat transfer between ice, water and steam. if there is 2kg of ice at -18c, 10kg of water at 25c and 1kg steam at 100c. assume there is no heat loss to the surrounding. specific latent heat of fusion for water lf = 3.34 × 105 j kg-1, specific latent heat of vaporization for water lv = 2.26 × 106 j kg-1, specific heat capacity of ice is 2100 jkg–1k–1, specific heat capacity for water c = 4200 j kg-1 c-1.
(a) a minimal portion of water is added to melt all the ice. how many kg of water is
required?
(b) a minimal portion of steam is added to melt all the ice. how many kg of steam is required?
(c) what is the final temperature (c) when all the ice and water mix with each other?
