WebMelting point: −48 °C (−54 °F; 225 K) Boiling point: 139 °C (282 °F; 412 K) WebSolution We start with the known volume of sweat (approximated as just water) and use the given information to convert to the amount of heat needed: 1.5L × 1000g 1L × 1mol 18g × 43.46kJ 1mol = 3.6 × 103kJ. Thus, 3600 kJ of heat are removed by the evaporation of 1.5 L of water. Exercise 7.2.5: Boiling Ammonia. WebBoiling Point: 39.8-40 °C mm Hg(lit.) Density: 1.325 g/mL at 25 °C(lit.)
