Stoichiometry The forces causing the vaporisation of liquid are derived from the Kinetic energy of translation of its molecules. The heat of vaporisation Both B & C Increases with pressure rise Becomes zero at the critical point Decreases with increasing pressure Both B & C Increases with pressure rise Becomes zero at the critical point Decreases with increasing pressure ANSWER DOWNLOAD EXAMIANS APP
