How much heat is needed to convert 80 g of ice initially at -10⁰C into 60g of water and 20 g of steam at 100⁰C.
Data:
- Specific latent heat of melting ice and that of water vaporization: Lf = 334 kJ / kg and Lv = 2260 kJ / kg
- Thermal mass capacity of water, ice and that of water vapor: cwater = 4.2 kJ / kg.K; cice = 2.1 kJ / kg.K and cvapor = 2.0 kJ / kg.K
