Question

The outer surface of a beaker containing ice cubes becomes wet in a short while

Answer 1

yes yes when we pour ice cubes in a a beaker then,the outer surface containing ice cubes become wet in a short period of time

Answer 2

Answer:

1) when ice cubes are placed in a beaker ice starts melting. the heat required for melting is absorbed form the surrounding air and also from the beaker to some extent . hence the temperature of the air and beaker falls.

2) the capacity of air to hold water vapour depends upon the temperature of air and this capacity decreases as. the temperature decreases .

3) At a certain low temperature , the surrounding air beacomes saturated with water vapour present in it .

As the temperature falls further, the air is unable to hold all the water vapour.

4) hence, the extra water vapour starts condensing on the cold outer surface of the beaker in the form of minute drops . therefore , the outer surface of the beaker containing ice cubes becomes wet in a short while.
