Stoichiometry A gas at 0°C was subjected to constant pressure cooling until its volume became half the original volume. The temperature of the gas at this stage will be 0°C -136.5°C 0°K -136.5°K 0°C -136.5°C 0°K -136.5°K 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 not lose energy on collision Do work equal to loss in kinetic energy Are above the inversion temperature Do not exert attractive force on each other Do not lose energy on collision Do work equal to loss in kinetic energy Are above the inversion temperature Do not exert attractive force on each other ANSWER DOWNLOAD EXAMIANS APP
