What is the effect of temperature on: (i) surface tension (ii) viscosity.
Surface tension and Viscosity both decrease with increase in temperature.
Arrange ether, water and ethyl alcohol in order of decreasing intermolecular attractive forces.
The heat of vaporisation of water at 100°C is 40·6 kJ per mole and that of benzene at 80°C is 31kJ per mole. Which out of the two has stronger attractive forces ?
