An inverse carnot cooling device extracts heat from a freezer compartment that has a temperature of -13. ° C and gives off that heat to the air in a living room with a temperature of 24. ° C. The compressor has a useful power of 150 W. What is the minimum time required to convert .24 kg of water at 24 ° C to ice at 0 ° C? (For data see tables in the ppt about calorimetry). Select the correct answer from the following list:

a) 1.65 minutes

b) 54.8 seconds

c) 26.3 seconds

d) 49.4 minutes
