4. (13 pts.) Any gas can, in theory, serve as a refrigerant, since the expansion of a gas always causes cooling. Ammonia (NH3) is no exception. Using the information provided in the table, along with your knowledge of chemistry, determine how much heat (in kJ) could be removed from inside a refrigerator if 2.00 kg of liquid ammonia were heated from -50.0C to 4.00C? AH transition, kJ/mol AH tus = 5.65 AHVAR 23.33 Temp. (C) = -77.73C Tbp = -33.3 C Specific heat (J/g -K) Sold = 5.11 - Liquid = 4.77 Gas = 2.24
