Solving a chemistry problem

Solving a chemistry problem

3. Using the dependence of the surface tension of the liquid on temperature (Table 2.1), determine the internal energy and entropy of the surface layer, the heat of formation of a unit surface and the critical temperature. What conclusions follow from the linear nature of the dependence b=f(T) and the negative sign of the temperature coefficient of surface tension?
Substance Surface tension b*103(N*m-1) at temperature C
0 10 20 30 40 50 60
Acetone 26.21 25.00 23.70 22.01 21.16 19.90 13.61
