How much heat, in joules, is required to convert 1.00 kg of ice at 0°C into steam at 100°C? (LF,ice = 333 J/g; LV,steam = 2.26 × 10³ J/g.)

To convert ice at 0°C to steam at 100°C, calculate the heat for melting ice, heating water, and vaporizing water. Melting: 1000g × 333 J/g = 3.33 × 10^5 J. Heating: 1000g × 4.18 J/g°C × 100°C = 4.18 × 10^5 J. Vaporizing: 1000g × 2.26 × 10^3 J/g = 2.26 × 10^6 J. Total: 3.33 × 10^5 + 4.18 × 10^5 + 2.26 × 10^6 = 3.01 × 10^6 J.
