Please answer the following question(s): 1. (a) How much heat transfer is necessary to raise the temperature of a 0.14 -kg piece of ice from-16 °C to 140 °C, including the 20 kJ/s energy needed for phase changes? Specific heat of ice = 2.090 kJ/kg °C Specific heat of water = 4.186 kJ/kg °C Specific heat of steam = 1.520 kJ/kg °C Heat of fusion of water = 334 kJ/kg Heat of vaporization = 2256 kJ/kg (1) Heat needed to warm ice to 0 °C: Q₁: KJ (ii) Heat needed to melt ice at 0 °C: Q₂: kJ (ii) Heat required to warm 0 °C water to 100 °C: Q3: KJ (iv) Heat required to vaporize water at 100 °C: Q kJ (v) Heat required to warm 100 °C vapor to 140 °C: Q5: kJ Total heat, Q: kJ (b) How much time is required for the entire process, assuming a constant 20.0 kj/s rate of heat transfer? Total time, t 3
