Vapour is injected at a uniform rate in ...

Vapour is injected at a uniform rate in a closed vessel which was initially evacuated. The pressure in the vessel

A

Increases continuously

B

Decreases continuously

C

First increases and then decreases

D

First increases and then becomes constant

Text Solution

Verified by Experts

The correct Answer is:
C
Since, number of moles increases, pressures increases and at certain pressure vapour condenses hence pressure now decreases.

A gas is enclosed in a vessel of volume V at temperature T_(1) and P, the vessel is connected to another vessel of volume V//2 by a tube and a stopcock. The second vessel is initially evacuated. If the stopcock is opened, the temperature of second vessel becomes T_(2) . The first vessel is maintained at a temperature T_(1) . What is the final pressure P_(1) in the apparatus ?

A vacuum pump has a cylinder of volume upsilon and is connected to a vessel of volume V to pump out air from the vessel The initial pressure of gas in vessel is P Show that after n strockes the pressure in vessel is reduced to P_(n) = P[(V)/(V+v)]^(n) .

A vessel A has volume V and a vessel B has volume 2V. Both contain some water which has constant volume. The pressure in the space above water is p_(a) for vessel A and p_(b) for vessel B.

A closed vessel is maintained at a constant temperture. It is first evacuated and then vapour is injected it continuously. The pressure of the vapour in the vessel

If two liquids A ( P_A^(@) =100 torr) and ( P_B^(@) =200 torr ) which are completely immiscible with each other (each one will behave indepenently of the othere)are present in a closed vessel, the total vapour pressure of the system will be :

A certain vessel X has water and nitrogen gas at a total pressure of 2 atm and 300 K . All the contents of vessel and transferred to another vessel Y having half the capacity of the vessel X . The pressure of N_(2) in this vessel was 3.8 atm at 300 K . The vessel Y is heated to 320 K and the total pressure observed was 4.32 atm. Assume that the volume occupied by the gases in vessel is equal to the volume of the vessel. Calculate the following: Pressure of water vapour at 320 K .
