A glass of 450.0 g water at 20°C is chilled using a 20.0 g icecube at 0°C. Assume that the mixing happens under constant pressure and sufficiently f so that no heat is exhanged between the content of the glass and its surroundings. Calculate the entropy change of the universe (water and icecub as result of the mixing process.
