The outer surface of a beaker containing ice cubes becomes wet in short while - Give scientific reason.

By
Question  The outer surface of a beaker containing ice cubes becomes wet in short while. Answer  When ice cubes are placed in a beaker, ice starts melting.  The heat required for melting is absorbed from the surrounding air and also from the beaker to some extent.  Hence, the temperature of the air and beaker falls.  The capacity of air to hold water vapour depends upon the temperature of the air, and this capacity decreases as the temperature decreases.  At a certain low temperature, the surrounding air becomes saturated with water vapour present in it.  As the temperature falls further, the air is unable to hold all the water vapour.  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.

Low And High Tides 



                               Do You Know: Low And High Tides




INFORMATION:- 

                            You must be knowing about the high and low tides that occur regularly in the sea. The level of sea water at any given location along sea shore increases and decreases twice a day at regular intervals. high and low tides occur at different types of water in the sea changes because of the gravitational force exerted by the moon. 

                            Water directly under the moon gets pulled towards the moon and the level of water there goes up causing high and low tide at that place. At two places on the earth at ninety degree from the place of high tide, the level of water is minimum and low tides occur there as shown in upper figure.

With a specific initial velocity, we can jump higher on the moon than on the earth, give scientific reason.

Question What is Gravitational Force What is the value of g GIVE REASON : With a specific initial velocity, we can jump higher on the moon than on the ea rth.               Answer what is High and low tides what is weightlessness in space Gravitational waves  The acceleration due to gravity on the moon is 1/6 of that on the earth. Hence, with a specific initial velocity, we can jump higher on the moon than on the earth. This can be seen from the equation h=u^2/2g. Other Questions like this  (1) The weight of an object changes from place to place though its mass is constant. (2)   If a feather and a stone are released from the top of a building simultaneously, the stone reaches the ground earlier than the feather .

 The Weightlessness In Space  Gravitational waves     DO YOU KNOW: THE WEIGHTLESSNESS IN SPACE What is the value of g What is Gravitational Force INFORMATION:                           Space travellers  as well as objects in the spacecraft pppear to be floating. Why does this happen? though the spacecraft is a height from the surface of the earth, the value of 'g' there is zero(0).                             In the space station the value of 'g' is  only 11% less than it's value on the surface of the Earth. Thus, the height of a spacecraft is not the reason for their weightlessness. their weightlessness is caused by their being in the state of free fall.                            Though the spacecraft is not falling on the earth because of...

The Value Of 'g' what is weightlessness in space                                               DO YOU KNOW: THE VALUE OF 'g' INFORMATION:-   What is Gravitational Force                         The value of g is the same for all object at a given place on the earth. thus, any two objects, irrespective of their masses or any other properties, when dropped from the same height and falling freely will reach the earth at same time. Galileo is said to have performed an experiment around 1590 in the Italian of Pisa. He dropped two spheres of different masses from the learning tower of Pisa to demonstrate that both spheres reached the ground at the same time. what is High and low tides   Gravitational waves                          when we drop a ...

Gravitation force

  Gravitational Force what is High and low tides   The phenomenon of a gravitation was discovered by Sir Issac Newton. As the story goes, he discovered the force by seeing an apple fall from a tree on the ground. He wondered why all apples fall vertically downward and not an angle to the vertical. Why do they not fly in a horizontal direction? Gravitational waves  After much thought, he came to the conclusion that the earth must be attracting the apple towards itself and this attractive force must be directed towards the center of the earth. The direction from the apple on the tree to the center if the earth is vertical direction at the position of the apple and thus, the apple falls vertically downwards. what is weightlessness in space On the up side shows an apple tree on the earth. The force on an apple on the tree is towards the center of the earth i.e. along the perpendicular from the position of the apple to the surface of the earth. The figure also shows the gravit...

Similarly you must have seen the waves generated on a string when both its end are held in hand and it is shaken. Light  is also type of wave called the ELECTROMAGNETIC WAVE. Gamma rays, X-rays, ultraviolet rays, infrared rays, microwaves and radioactive waves are all different types of ELECTROMAGNETIC WAVES. Astronomical objects emit these waves and we receive them using our instruments.

Those are called as Disaster. Some of the main natural disasters are floods, wet and dry famine, cyclone, earthquakes, volcanoes, etc. These are 'all of a sudden' troubles to the mankind. such events cause sudden changes in the environment and thereby cause the damage to it. Environment is also damaged due to use of natural resources for our development. This leads to sudden disaster. Un expected to human. This can called man made disaster.                                        United nations has defined the disa...

Effects of water pollution 1)Pathogenic and non pathogenic organisms are present in polluted drinking water. 2)Water born disaster such as cholera, typhoid, diarrhea, dysentery, hepatitis, polio, and  jaundice can be caused due to pathogens. 3)Water pollution affect on aquatic life. a) Oil pollution affect algae. b) Reduction in dissolved oxygen can kill fishes. c) Pesticides affect reproduction and growth of fishes. d) Detergents cause harm to the respiratory system of fishes. Effects of soil pollution  1) Soil erosion retarded growth of plants/crops. 2)Nutrition deficiency. 3) Loss of fertility and productivity of soil. 4) Sewage sludge containing harmful bacteria can cause infections and diseases. 5) Radio active soil pollutants can enter into crops, animals and humans through the food chain.
