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

The temperature at which a liquid boils is the boiling Water > Ethanol > Ammonia
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
