Malia was able to make a paperclip float on the surface of water. What will most likely happen to the paperclip if a drop of dis

hwashing detergent is added near it?
Soap is a surfactant that increases the intermolecular forces of water allowing the paperclip to continue to float.
Soap makes the water less viscous making the paperclip sink.

For water ∆H°vap = 40.7 kJ/mol at 100.°C, its boiling point. Calculate ∆S° for the vaporization of 1.00 mol water at 100.°C and
damaskus [11]

Answer : The value of change in entropy for vaporization of water is 1.09\times 10^2J/mol

Explanation :

Formula used :

\Delta S^o=\frac{\Delta H^o_{vap}}{T_b}

where,

\Delta S^o = change in entropy  of vaporization = ?

\Delta H^o_{vap} = change in enthalpy of vaporization = 40.7 kJ/mol

T_b = boiling point temperature of water = 100^oC=273+100=373K

Now put all the given values in the above formula, we get:

\Delta S^o=\frac{\Delta H^o_{vap}}{T_b}

\Delta S^o=\frac{40.7kJ/mol}{373K}

\Delta S^o=1.09\times 10^2J/mol

Therefore, the value of change in entropy for vaporization of water is 1.09\times 10^2J/mol
