he shape of a liquid’s meniscus is determined by A) the volume of the liquid B) the amount of hydrogen bonding in the liquid C) the viscosity of the liquid D) the type of material the container is made of E) the relative magnitudes of cohesive forces in the liquid and adhesive forces between the liquid and its container 22) How high a liquid will rise up a narrow tube as a result of capillary action depends on A) only the magnitude of adhesive forces between the liquid and the tube B) gravity alone C) only the magnitude of cohesive forces in the liquid D) the magnitudes of cohesive forces in the liquid and adhesive forces between the liquid and the tube, and gravity E) the viscosity of the liquid 23)
The property responsible for the “beading up” of water is A) vapor pressure B) viscosity C) hydrogen bonding D) surface tension E) density 24) A volatile liquid is one that A) is highly cohesive B) is highly viscous C) is highly hydrogen-bonded D) readily evaporates E) is highly flammable increases. 25) In general, the vapor pressure of a substance increases as A) viscosity B) hydrogen bonding C) temperature D) surface tension E) molecular weight 26) The vapor pressure of any substance at its normal boiling point is A) equal to the vapor pressure of water B) 1 torr C) 1 atm D) 1 Pa E) equal to atmospheric pressure 27) Some things take longer to cook at high altitudes than at low altitudes because A) water boils at a lower temperature at high altitude than at low altitude B) there is a higher moisture content in the air at high altitude C) heat isn’t conducted as well in low density air D) natural gas flames don’t burn as hot at high altitudes E) water boils at a higher temperature at high altitude than at low altitude.
