A mass of m=1kg of steam is contained in a closed rigidcontainer. Initially the pressure and temperature of the steam are:p1= 1.5 MPa and t1=240?C, respectively. Then the temperature dropsto 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)percentage of volume that is occupied by the saturated liquid atthe final state, c) heat transfer with the surroundings per unitmass of the system. For: p=1.5 MPa and T1=240?C: h1=2900KJ/kg,v1=0.1483 m3/kg while for T2=100?C: h’=419KJ/kg, v’=0.001043m3/kgand h”=2676 KJ/kg ,v”=1.672 m3/kg.
