Which state of matter is characterized by having molecules close together, but moving
randomly?
*liquid
*gas
*solid
*all of these - ANSliquid
Which state of matter is characterized by having molecules far apart and moving randomly?

The temperature at which a liquid boils is the boiling point of the liquid. The boiling point is an
indication of the intermolecular forces that hold the matter in the liquid state. Water, H2O, boils
at 100°C. Ethanol, C2H6O boils at 78°C. Ammonia, NH3, boils at -33°C. Which one of the
following ranks the intermolecular forces in these liquids from the strongest to the weakest?
*Water > Ammonia > Ethanol
*Water > Ethanol > Ammonia
*Ethanol > Water > Ammonia
*Ammonia > Ethanol > Water - ANSWater > Ethanol > Ammonia
