QUESTION:
On a sunny day, large “bubbles” of air form on the sun-warmed earth, gradually expand, and finally break free to rise through the atmosphere. Soaring birds and glider pilots are fond of using these “thermals” to gain altitude easily. This expansion is essentially an adiabatic process. Why?
ANSWER:Solution 16DQ Step 1: An adiabatic process is simply one in which no heat is added or subtracted from the fluid.but there are lots of processes that mess up the flow in a way you can undo the effects. Example: Running an egg-beater in the fluid will not be reversible.
