Select the correct statements:a)Pressure of saturated vapours is indep...

a) Pressure of saturated vapours is independent of their volume at constant temperature.

b) Saturation vapor pressure (or the maximum amount of water vapor that can be in the air) increases exponentially as temperature increases. The sharp increase in saturation vapor pressure with increasing temperature continues beyond 40°C (104°F).

c) When a given volume of air is made more moist by adding water molecules, heavier molecules are replaced with lighter molecules. Therefore, moist air is lighter than dry air if both are at the same temperature and pressure.

d) "During a change in state the heat energy is used to change the bonding between the molecules. In the case of melting, added energy is used to break the bonds between the molecules. In the case of freezing, energy is subtracted as the molecules bond to one another. These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules.

"If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water. Immediately after the molecular bonds in the ice are broken the molecules are moving (vibrating) at the same average speed as before, so their average kinetic energy remains the same, and, thus, their Kelvin temperature remains the same."
