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