Concept explainers
(a)
Interpretation:
The change in vapor pressure of water in a closed beaker has to be predicted when –
Temperature is lowered
Concept Introduction:
When a liquid is boiled, the molecules from liquid phase enter into vapor phase. This phenomenon is called evaporation. Vapor pressure is defined as the pressure exerted by the molecules in the vapor phase of the liquid that is in equilibrium with the liquid phase.
(b)
Interpretation:
The change in vapor pressure of water in a closed beaker has to be predicted when –
Volume of the beaker is doubled
Concept Introduction:
When a liquid is boiled, the molecules from liquid phase enter into vapor phase. This phenomenon is called evaporation. Vapor pressure is defined as the pressure exerted by the molecules in the vapor phase of the liquid that is in equilibrium with the liquid phase.
(c)
Interpretation:
The change in vapor pressure of water in a closed beaker has to be predicted when –
More water is added to the beaker.
