Question

What is the entropy change during the transformation of I2 (s, 1atm 298K) into I2(v, 1 atm 457k) Δ H fusion= 15.68kJ/mole Δ H vap=25.522 kJ/mole m.p= 113.6oC and b.p= 184oC. Cp=81.58J/K/mol for I2 (l) and Cp= 60.24 for I2 (s) .​

even i am searching for the same answer if got please share

Answer 2

Explanation:

There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction ("stiction") between non-moving surfaces, and kinetic friction between moving surfaces.
