Consider the following eight two-dimensional data points: x1: (23, 12), x2: (6, 6), x3: (15, 0), x4: (15, 28), x5:(20, 9), x6: (8, 9), x7: (20, 11), x8: (8, 13), If k = 2 and the initial means are (20, 9) and (8, 9), what is the output of the algorithm after 2 iterations? In the output, you are required to show the information about each final cluster (including the mean of the cluster and all data points in this cluster.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
