Hello sir I solve this question by method written below.. please let me know if I am doing right.. 25 32 48 82 x 32-25=7 48-32=16 82-48=34 7 16 34 I have taken it as (7+1)*2= 16 (16+1)*2=34 and (34+1)*2=70 so value of x = 82+70 i.e. 152
Why we treated vfg as volume

Becoz it is a phase change
sir a condition is given that ∆Q/T =0 and ∆S greater than 0 and in options​ it is given that is it reversible adiabatic or irreversible adiabatic

it's a contradictory Question.... is there any other options?

see if ∆S(system or surrounding)>0 and ∆Q/T=0 then it may or may not be reversible.... if Q is zero then it is a adiabatic process.... if ∆s(universe)>0 then it is irreversible...

  3. The vapour pressure of liquid ammonia (in atmosphere) in the vicinity of the triple point can be expressed as 3063-15.16 where temperature T is expressed in K In a similar manner, the vapour pressure of solid ammonia can be expressed as In p +--=18.7 Take the molecular mass of ammonia to be 17 kg/kmol Q.1 The temperature and pressure at the triple point are (B) 295.2 K, 0.59 atm (D) 195.2 K, 0.59 atm (A) 295.2 K, 0.69 atm (C) 195.2 K, 0.69 atm The latent heat of vapourization is (A) 1298 kJ/kg Q.2 (B) 1398 kJ/kg (C) 1498 kJ/kg (D) 1698 kJ/kg
