Stoichiometry One kg of saturated steam at 100°C and 1.01325 bar is contained in a rigid walled vessel. It lias a volume of 1.673 m³. It cools to 98°C ; the saturation pressure is 0.943 bar ; one kg of water vapour under these conditions has a volume of 1.789 m³. The amount of water vapour condensed (in kg) is 0.065 1 0.1 0.065 1 0.1 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 Do not exert attractive force on each other Are above the inversion temperature Do work equal to loss in kinetic energy Do not lose energy on collision Do not exert attractive force on each other Are above the inversion temperature ANSWER DOWNLOAD EXAMIANS APP
