In an insulated vessel
In a pitcher when a water is filled some water comes to outer surface slowly through its porous walls and gets evaporated. Most of the latent heat needed for evaporation is taken from water inside and hence this water is cooled down. If 10 kg water is taken

In a pitcher when a water is filled some water comes to outer surface slowly through its porous walls and gets evaporated. Most of the latent heat needed for evaporation is taken from water inside and hence this water is cooled down. If 10 kg water is taken 0.05 kg steam at 373 K and [...]
The apparatus shown in the figure consists of four glass columns connected by horizontal section. The height of two central column B and C are 49 cm each. The two outer columns A and D are open to the temperature. A and C are maintained at a temperature of 95C while the columns B and D are maintained at 5C. The height of the liquid in A and D measured from the base the are 52.8 cm and 51cm respectively.
