Stoichiometry A liquid is in equilibrium with its vapor at its boiling point. On an average, the molecules in the liquid and gaseous phases have equal Total energy Intermolecular forces of attraction Potential energy Kinetic energy Total energy Intermolecular forces of attraction Potential energy Kinetic energy ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Unrestrained expansion of an ideal gas does not result in its cooling due to the reason that the gas molecules Do work equal to loss in kinetic energy Do not lose energy on collision Are above the inversion temperature Do not exert attractive force on each other Do work equal to loss in kinetic energy Do not lose energy on collision Are above the inversion temperature Do not exert attractive force on each other ANSWER DOWNLOAD EXAMIANS APP
