Public hugeint modnine (): returns the remainder of the integer stored in the linked list when dividing it by 9. the easiest way to find the remainder of an integer like 235 when dividing it by nine is to calculate the remainder of 2+3+5 instead. use this idea to implement modnine method. method modnine must be able to calculate the remainder of a huge integer like 10 − 1 when being divided by 9. for example, modnine (10 − 1) first sums the digits of the input integer and then calls itself for the calculated sum. it does the same operations recursively until it reaches a one-digit integer. see below for details: modenine (10 − 1) =modenine (99 . . 9) times=modenine ()=modenine (45)=modenine (9)=0;

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.
