Properties Of Liquids And IMF Flashcards
To learn about everything (20 cards)
give rise to a number of structural features and properties of liquids.
IMF
Properties of liquid
Surface tension
Viscosity
Solubility
Amount of energy required to stretch or increase the surface of the liquid by a unit area.
Surface tension
Attraction between like molecules
Cohesion
Attraction between unlike molecules
Adhesion
is the liquid’s resistance to flow
Viscosity
The _____ the IMF, the ______ the viscosity
Higher, higher
have much higher viscosity than any other liquids because of its structure.
Glycerol/glycerin
It is the pressure exerted by a vapor with its condensed phases. It is expressed in pressure units, atm.
Vapor pressure
All liquids exert a vapor pressure with or without heat.
True
All liquids exert a vapor pressure only without heat.
False
The _____ the IMF, the _____ the vapor pressure of a liquid at a given temperature.
Stronger, lower
is the tendency of a substance to vaporize.
Volatility
tend to vaporize more easily.
Volatile liquids
The _______ the volatility, the _______ is the vapor pressure.
Higher/lower, higher/lower
The _______ is the strength of the IMF that exists in the liquid, the ______ the molar heat of vaporization.
Greater, higher
is the temperature at with the substance boil at an external temperature of 1 atm or 760 mmHg.
Normal boiling point
changefrom one state (solid or liquid or gas) to another without achangein chemical composition.
Phase change
Occurs when energy is either added or removed from a substance.
Phase change
energy required to raise the temperature of water to 1 degree Celsius.
Specific heat capacity
