Stoichiometry A vessel of volume 1000 m³ contains air which is saturated with water vapour. The total pressure and temperature are 100 kPa and 20°C respectively. Assuming that the vapour pressure of water at 20°C is 2.34 kPa, the amount of water vapour (in kg) in the vessel is approximately 25 17 20 34 25 17 20 34 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 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 Do not lose energy on collision ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Enthalpy change resulting, when unit mass of solid is wetted with sufficient liquid, so that further addition of liquid produces no additional thermal effect, is called the heat of Adsorption Complete wetting Wetting Mixing Adsorption Complete wetting Wetting Mixing ANSWER DOWNLOAD EXAMIANS APP
