Two identical refrigerators are plugged in for the first time. Refrigerator A is empty (except for air), and refrigerator B is filled with jugs of water. The compressors of both refrigerators immediately turn on and begin cooling the interiors of the refrigerators. After two hours, the compressor of refrigerator A turns off while the compressor of refrigerator B continues to run. The next day, the compressor of refrigerator A can be heard turning on and off every few minutes, while the compressor of refrigerator B turns off and on every hour or so (and stays on longer each time). Explain these observations.

This question is about 2 figurate us leg out a and b, so they are the same thing and they are plug in for the first time and a is empty, so i has a ha inside it and b is filled with a jug of water. So the compress of a tree to it does then on and began qualitate after after 2 hours, the compressor who referred 8 times half while i compressor fitter, continues to wrong and then the next day the compressor of todi can be tuning on and off every 3 Minutes why the compress of otoes of and haunt every hollow soul? So we are told to explain this observation soanies. We need to know what the specificate capacity of air is well. We know that he is very plain, so the specialities capacity for a is 1.0 joules per gram degrees celsius and for watts 4.1 is 4 degrees. We can see from here that the specific heat capacity of water is higher than the specific capacity here, and that means that you will need 4.14 joules of energy to raise the temperature of water by 1 degree. Celsius. 1 gram of water. The lot, which is why you need 1.0 joules energy- to raise the temperature by 1 degree celsius 1 gram of 1 degree celsius. So that means you need more energy and water than in her, and that is the reason that on the first day when he drew the figurato ton hon after 2 hours, the compressor etons hot, because the d d, specific capacity of air is very like than water. So this gets cooled first gets cooled quickly and this will take a longer time and then, on the next day the compress of can be hacked on the onofvery a few minutes. So i was tongoni half of a few minutes because it not stabilize while with 1 on and off over a few hours due to the specific of water and it's a small, stable minus hold, unlike that, can easily warm up and can easily cool down. Because of this small energy, that's required to raise to 1 gram or life base that man, the summon energy to raise this 1 gram to raise the temperature of 1 gram of water set the compressor of a 10 of the first day first, compared to b, because The specific capacity of a is lower than specific capacity of water and then the compressure of a was telling on a half the next day, because this is very small. So you can bring down the temperature by 1 degree celsius with temperature, 1 gray, 1 degree celsius. With just 1.0 joules and then it's going put 3 was off again by the 1.0 joules, and that is why it goes like every minute. Compare 2 days of water, which is 4.184 point, so it is, can go like down 1 or an then come in the next 1, because the energy difference is larger.
