Which of the following statements about volatility are true? Select all that apply. Pick 3
Volatility is a measure of how easily a liquid evaporates.
Volatile liquids have a large number of molecules in the gas phase above the liquid.
Stronger intermolecular forces result in lower volatility.
Volatile liquids have a small number of molecules in the gas phase above the liquid.
Stronger intermolecular forces result in higher volatility.
Volatility is a measure of how easily a liquid condenses.
