An open vessel at 270 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 :
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 vapor pressure at that temperature is called saturated vapor pressure.
As we have learned in the gaseous state
we know air escaped for vessel, air reamain
in vessel.
P,V constant
