1. Why does water boil at 100oC at 760 mm Hg pressure?
2. Vapour pressure of water is 27.8 mm Hg at 298 K. Calculate the vapour pressure ofwater at 310 K. Molar heat of vaporisation is 43.99 kJ/mol.
3. In your experiment, the manometer is used for knowing the pressure inside the flask,F. What will be the pressure inside if: (Assume the atmospheric pressure to be 760mm Hg).(i) levels on both sides of the manometer are same(ii) the difference in the levels on the two sides is 300 mm
4. Convert the atmospheric pressure to atmospheres and pascals
