A block of ice is floating in a cup of water. It is 0.5 cm above the water surface and its length and width are 2cm each. Given that the density of ice is 900 kgm 3 and the density of the
water is 1000 kgm3, find the volume of the ice block.

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.
