A 1 m^3 closed container contains air with vapor pressure 10hPa. a dish containing 8 g of liquid water is placed in the container. a thermostat maintains the temperature of the air within the container at 25 degree Celsius at all times. In the following, assume a latent heat of vaporization of 2.4*10^6 J/kg.

Will all the water in the dish eventually evaporate?

If the container holds 1.3 kg of dry air, what are the final specific and relative humidities of the air in the container? what is the dew point?

The experimental values of saturated vapour pressure and density at given temp. are constants and are given in tables

The copy of the table from 'Selected questions and problems in physics' by R Gladcova, Mir Publication Moscow is also attached.

Please see the attached files.

The air is having the vapour pressure 10hPa = 1 kPa.
The saturated vapour pressure at 25 C is 3.173 kPa and the density is 23.0 x 10 kg/m .
Therefore the water vapour present in the ...
