Stoichiometry Unrestrained expansion of an ideal gas does not result in its cooling due to the reason that the gas molecules Do not exert attractive force on each other Do not lose energy on collision Are above the inversion temperature Do work equal to loss in kinetic energy Do not exert attractive force on each other Do not lose energy on collision Are above the inversion temperature Do work equal to loss in kinetic energy ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry At a constant volume, for a fixed number of moles of a gas, the pressure of the gas increases with rise of temperature due to Increase in average molecular speed Increase in molecular attraction Decrease in mean free path Increased collision rate among molecules Increase in average molecular speed Increase in molecular attraction Decrease in mean free path Increased collision rate among molecules ANSWER DOWNLOAD EXAMIANS APP
