Liquid ammonia (boiling point = -33.4°C) can be used as arefrigerant and heat transfer fluid. How much energy is needed toheat 40.0 g of NH3(l) from -70.0°C to -20.0°C? The givens: -Specific heat capacity, NH3(l): 4.7 J/(g•K) - Specific heatcapacity, NH3(g): 2.2 J/(g•K( - Heat of vaporization: 23.5 kJ/mol -Molar mass: 17.0 g/mol
