1. ### Radius of Gyration of an H-polymer?

Hello, I've been struggling with determining the radius of gyration of an H-polymer. Show that the radius of gyration of an ideal H-polymer with all five sections containing an equal number (N/5) of Kuhn monomers of length b is: (R_g)^2 = (Nb^2/6)(89/625) I know the definition of the...
2. ### Why units of enthalpy of fusion might matter in statistical modelling

Hi I would like to know in which units enthalpy of fusion (Hf) should be expressed in statistical models (i.e. MLR) and why ? Should it be expressed in J/g or kJ/mol ? I will be very grateful for an easy to understand expatiation for non physicist.
3. ### Entropy:A concept that is not a physical quantity （Published in SCI-E Journal）

《Entropy : A concept that is not a physical quantity》 This study has demonstrated that entropy is not a physical quantity, that is, the physical quantity called entropy does not exist. If the efficiency of heat engine is defined as η = W/W1, and the reversible cycle is considered to be the...
