Why are intermolecular forces generally much weaker than bonding forces?
What is capillary action? How does it depend on the relative strengths of adhesive and cohesive forces?
Water (a) âwetsâ some surfaces and beads up on others. Mercury (b), in contrast, beads up on almost all surfaces, Explain this difference?
When a thin glass tube is put into water, the water rises 1.4 cm. When the same tube is put into hexane, the hexane rises only 0.4 cm, explain the difference?
Why is vaporization endothermic? Why is condensation exothermic?
Is fusion exothermic or endothermic? Why?
Calculate the amount of heat required to completely sublime 91.0 g of solid dry ice (CO2) at its sublimation temperature. The heat of sublimation for carbon dioxide is 32.3 kJ/mol.
Why is the heat of vaporization of water greater at room temperature than it is at its boiling point?
