In order to determine the quality of wet steam, by a separating and throttling calorimeter, the steam should be throttled such that the final state is
The process of sublimation is found to occur in case of
The slope of sublimation curve on P-Tdiagram for all substances is
In P-V-Tsurface, the zone below the triple point is known as
For which of the following substances, the gas laws can be used with minimum error?
The point that connects the saturated liquid line to the saturated vapour line is called
At triple point of a pure substance
The Triple point is a line on the P - v diagram where all the three phases solid, liquid and gases exist in equilibrium. At a pressure below the triple point line, the substance cannot exist in liquid phase and the substance when heated, transforms from solid to vapour by absorbing the latent heat of sublimation from the surroundings.
During throttling process
Sublimation curve on P-T diagram for all substances possesses the following slope
This is true for all substances.
At critical point the enthalpy of vapourization is
At critical point enthalpy of vapourization is zero i.e. liquid can directly converted into vapour (without any latent heat transaction).
