The surface tension and viscosity of water at several different temperatures are given in this table.
(a) As temperature increases, what happens to the surface tension of water? Explain why this occurs, in terms of molecular interactions and the effect of changing temperature.
(b) As temperature increases, what happens to the viscosity of water? Explain why this occurs, in terms of molecular interactions and the effect of changing temperature.
The density of liquid NH3 is\({\rm{0}}{\rm{.64}}\)g/mL; the density of gaseous NH3 at STP is\({\rm{0}}{\rm{.0007}}\)g/mL. Explain the difference between the densities of these two phases.
Ammonia can be liquefied by compression at room temperature; oxygen cannot be liquefied under these conditions. Why do the two gases exhibit different behaviour?
Identify two common observations indicating some liquids have sufficient vapor pressures to noticeably evaporate.
On the basis of intermolecular attractions, explain the differences in the boiling points of n-butane \(\left( { - 1 ^\circ C} \right)\) and chloroethane \(\left( {12 ^\circ C} \right),\)which have similar molar masses.
