specific heat of water is 4.186 kJ/kgC
specific heat of ice is 2.06 kJ/kgC
specific heat of steam is 2.1 kJ/kgK
heat of fusion of ice is 334 kJ/kg
heat of vaporization of water is 2256 kJ/kg
The above is all you need to answer this.
Hello gucci :
————————————————-
( 1 ) boiling water to steam [ 2257 kJ per kg ]
( 2 ) ice water to boiling water [ 420 kJ per kg ]
( 3 ) ice to ice water [ 334 kJ per kg ]
Water heat of vaporization = 2257 kJ per kg
Water specific heat = 4.2 kJ per kg
Water heat of fusion = 334 kJ per kg
