The most common type of mirage is an illusion that light from faraway objects is reflected by a pool of water that is not really there. mirages are generally observed in deserts, when there is a hot layer of air near the ground. given that the refractive index of air is lower for air at higher temperatures, explain how mirages can be formed.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
