The free energy change associated with homogeneous nucleation of a sphere (assume the radius as 5m) has an interfacial energy term and a volume free energy. Calculate the value of the interfacial term if the interfacial energy is given as (1/п) kJ/m2Kmol?
There is an increase in free energy due to interfacial energy is known as a capillarity effect or the Gibbs-Thomson effect. Find the increase in this free energy if the interfacial energy, the molar volume and the radius of the spherical particle are given as 10 (kJ/mm2), 6mm3/mol and 4mm respectively?
Consider for simplicity a wire frame suspending a liquid film. If one bar of the frame is movable it is found that a force 5N per unit length must be applied to maintain the bar in position. If this force moves a small distance so that the total area of the film is increased by 0.5m2. Interfacial free energy per unit area is given as 4 J/m2. Calculate the change in interfacial energy? (Take the area of interface as 2m2)
Estimate the interfacial solute concentration in the two liquids when the solute concentration is 45000 kg-moles/m3, interfacial solute concentration in liquid is 40000 kg-moles/m3, diffusivity is 2.5 × 10-11 m2/s and the length of the tube is 5m3 and the partition coefficient is 0.25.
A senior quality engineer during a training session trains his juniors about a particular common defect that has been found in their assembly.

A,B,C,D,E,G and I are seven friends who study in three different standards namely 5th, 6th and 7th such that not less than two friends study in the same standard. Each friend also has a different favorite subject namely History, Civics, English, Bangla, Science , Maths , and Economics but not necessarily in the same order. A likes Maths and studies in the 5th standard with only one other friend who likes Bangla. I studies with tow other friends . Both the friends who study with I like languages (Here languages include only Science , English and Bangla ) . D studies in the 6th standard with only one person and does not like Civics . E studies with only one friend . The one who likes history does not study in 5th or 6th standard . E does not like languages. C does not like English , Science or Civics. Which combination represents E's favorite subject and the standard in which he studies?
