An open vessel at 27o C is heated until two fifth of the air (assumed as an ideal gas ) in it has escaped from the vessel. Assuming that the volume of the vessel remains constant, the temperature at which the vessel has been heated is : (in K)
Ideal Gas Law in terms of density -
- wherein
where
d - density of gas
P - Pressure
R - Gas Constant
T - Temperature
M - Molar Mass
Saturated Vapour Pressure -
When equilibrium is attained between vapor and liquid kept in a partially filled beaker , the vapour pressure at that temperature is called saturated vapor pressure.
As we have learned in gaseous state
we know air escaped for vessel,
air reamain
in vessel.
