In which of the following phase change processes, kinetic energy of the particles increases ?
Open in App
Solution
The correct options are
A Sublimation
C Fusion
D Vaporization
∙ The order of kinetic energy of the particles : Gas > Liquid > Solid .
∙ Sublimation is a phase change process in which a solid is converted into gas. Therefore, kinetic energy of the particles increases.
∙ Fusion is a phase change process in which a solid is converted intoliquid. Therefore, kinetic energy of the particles increases.
∙ Vaporization is a phase change process in which a liquid is converted into gas. Therefore, kinetic energy of the particles increases.
∙Condensation is a phase change process in which a gas is converted into liquid. Therefore, kinetic energy of the particles decreases.
