Stoichiometry No cooling occurs, when an ideal gas undergoes unrestrained expansion, because the molecules Do work equal to loss in kinetic energy Exert no attractive force on each other Collide without loss of energy Are above the inversion temperature Do work equal to loss in kinetic energy Exert no attractive force on each other Collide without loss of energy Are above the inversion temperature ANSWER DOWNLOAD EXAMIANS APP
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 latent heat of condensation (kJ/kg⁻¹ ) under these conditions is 540 2676 40732 2263 540 2676 40732 2263 ANSWER DOWNLOAD EXAMIANS APP
