If you throw a raw egg at the wall, you’ll break the egg. But if you throw with the same speed into a sagging bed sheet, it won’t break. Why?
-The sheet is much “slicker” than the wall.
-The impact time when the egg strikes the sagging sheet is long so the impact force is small.
-The velocity of the egg decreases faster in the sheet than on the wall.
-The breaking egg caused a larger impact time, decreasing the force.

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.
