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
One simply multiplies 1,760 by 3 to find the answer of 5,280 feet. If one needs to find miles in inches, then one can multiply 5,280 feet by 12 inches per foot to find the answer of 63,360 inches. To make these calculations, one can use an online calculator or a miles to feet converter. Sources:
