While keeping your food cold, your refrigerator transfers energy from the inside to the surroundings. thus thermal energy goes from a colder object to a warmer one. what can you say about this? a. it is a violation of the second law of thermodynamics. b. it is not a violation of the second law of thermodynamics because refrigerators can have efficiency of 100%. c. it is not a violation of the second law of thermodynamics because the second law doesn't apply to refrigerators. d. the second law of thermodynamics applies in this situation, but it is not violated because the energy did not spontaneously go from cold to hot.
