Stoichiometry Gases diffuse faster compared to liquids because of the reason that the liquid molecules Are heavier Have no definite shape Move faster Are held together by stronger inter-molecular forces Are heavier Have no definite shape Move faster Are held together by stronger inter-molecular forces ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry No cooling occurs, when an ideal gas undergoes unrestrained expansion, because the molecules Exert no attractive force on each other Are above the inversion temperature Collide without loss of energy Do work equal to loss in kinetic energy Exert no attractive force on each other Are above the inversion temperature Collide without loss of energy Do work equal to loss in kinetic energy ANSWER DOWNLOAD EXAMIANS APP
