T-Mobile LTE 8:02 PM Assignment 10-1 : Attempt 1 Use IMF (intermolecular forces) to explain surface tension and capillary action Type your answer Question2 -12 Use IMF and explain why different liquids have different viscosity. How would temperature affect viscosity? Type your answer Question3 --13 Explain why liquids have vapor pressure. Explain how (1) IMF and (2) temperature affect vapor pressure Type your answer Question4 -13 Explain how metallic bonds occur. Describe the electron sea model and the band model (molecular orbital model). Can you use these models to explain the conductivity, malleability, ductility of metals? 0 of 4 completed Save for Later SubmitExplanation / Answer
(2) Different liquids have different magnitude of intermolecular forces so that they have different viscosities. The magnitude of intermolecular forces is directly proprtional to viscosity of theliquid.
(3) the parcticles (molecules/atoms) of Liquids have a tendency to escape from liquid into vapour and that vapour exerts some pressure on the surface of the liquid called vapor pressure.
Intermolecular forces magnitude is inversely proprtional to vapor pressure. If intermolecualr forces are strong then the escaping tendency is less and so the vapor pressure.
With increase in temperature , vapor pressure increases due to inceasing the escaping tendency.
(4) Usually in metals , the valence electrons are loosely bound and they are free to move along the lattice. Metallic bond occurs from the electrostatic attraction between free electrons and the metal cations.
metallic bonding is responsible for many properties of metals like ductility, luster, conductivity etc.
