alculate the change in the enthalpy of3.5 moles of Kryptonite (KyO7) in gas phase whenit is heated from 50°Cto 120°CatP= 3.7 atm.The associated molar heat capacity at constantpressure satisfies̄Cp=a0+b1T. The value ofthe coefficients are:a0= 25.503 J K−1mol−1,b1= 13.612×10−3J K−2mol−1

ll Verizon 99% 1:01 AM Done 3. A vessel containing 50 liters of saturated steam at 150 °C is cooled down to 25 °C. Using data from steam tables, determine the final mass and volume of the liquid water in the vessel. Calculate how much heat needs to be removed

A refrigerator has an ice tray compartment at -18.0°C and the room temperature is 20.2°C. The refrigerator can convert 37.7 g of water at room temperature to that many grams of ice at -18.0°C every minute. If the specific heat of ice is 2.09 kJ/kg.K, the specific heat of water is 4.186 kJ/kg.K, the latent heat of fusion is 333.2 kJ/kg and the power required is 82.5 W, what is the COP (cooling) of the refrigerator?
