a) among water and steam at the same temperature steam causes more harm as it has absorbed more heat energy in the form of latent heat of vaporization.
b) water in earthen pot becomes cool because earthen pots have small pores on the surface which allows water to escape via them during evaporation, the evaporated water takes away the heat from inside the earthen pot, which is again an example of latent heat of vaporization
