1 Adiabatic processes can occur if the container of the system has thermally-insulated walls or the process happens in an extremely short time.  For an adiabatically expanding ideal monatomic gas which does work on its environment (W is positive), internal energy of the gas should decrease.
ever wondered how many feet are in a mile well the answer is 5280 at least that is the answer unless you are talking about nautical miles then the answer is different so how many feet are in a nautical mile approximately 6076 miles
80 Feet to Miles = 0.0152: 3 Feet to Miles = 0.0006: 90 Feet to Miles = 0.017: 4 Feet to Miles = 0.0008: 100 Feet to Miles = 0.0189: 5 Feet to Miles = 0.0009: 200 Feet to Miles = 0.0379: 6 Feet to Miles = 0.0011: 300 Feet to Miles = 0.0568: 7 Feet to Miles = 0.0013: 400 Feet to Miles = 0.0758: 8 Feet to Miles = 0.0015: 500 Feet to Miles = 0.0947: 9 Feet to Miles = 0.0017: 600 Feet to Miles = 0.1136: 10 Feet to Miles = 0.0019: 800 Feet to Miles = 0.1515
