Stoichiometry Unrestrained expansion of an ideal gas does not result in its cooling due to the reason that the gas molecules Do not lose energy on collision Do work equal to loss in kinetic energy Do not exert attractive force on each other Are above the inversion temperature Do not lose energy on collision Do work equal to loss in kinetic energy Do not exert attractive force on each other Are above the inversion temperature ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry The net heat evolved or absorbed in a chemical process, i.e. total change in the enthalpy of the system is independent of the Temperature & pressure Number of intermediate chemical reactions involved None of these State of aggregation & the state of combination at the beginning & the end of the reaction Temperature & pressure Number of intermediate chemical reactions involved None of these State of aggregation & the state of combination at the beginning & the end of the reaction ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Pick out the wrong unit conversion. 1 kPa = 100 bar None of these 1 mm Hg = 1 torr = 133.3 Pa 1 atm. = 760 mm Hg = 29.92 inch Hg = 14.7 psi = 1.013 bar = 1.013 kgf/cm² 1 kPa = 100 bar None of these 1 mm Hg = 1 torr = 133.3 Pa 1 atm. = 760 mm Hg = 29.92 inch Hg = 14.7 psi = 1.013 bar = 1.013 kgf/cm² ANSWER DOWNLOAD EXAMIANS APP
