Problem 1: Consider 1 kg liquid water at temperature 298 K (specific weight 1 kg/L) filled in a closed glass vessel. Given the interfacial tension glass / water at this temperature is 0.07275 J/m2. Calculate the interfacial energy in case the glass vessel is
- A cube
- A sphere
- A circular cylinder 5 cm length.
Compare the results obtained and formulate a general statement about effect of the interfacial shape on its energy.
