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.

Points of chemical reaction {Unheard}

                                

                          Do You Know: Chemical Reaction

INFORMATION:-

Points:-

1.One or more chemical reactions takes place during every chemical change.

2.Some chemical reactions occur at fast speed whereas some occur at slow speed. 

3.Strong acid and strong base react instantaneously.

4.In our body, enzyme increase the rate of physiological reactions. 

5.Perishable Foodstuff gets preserved longer in a refrigerator. The rate of decomposition of foodstuff gets lowered due to low temperature, and its freshness is maintained. 

6.Vegitable cook quickly on oil rather than no water.

7.The chemical reactions are profitable in the chemical factories if their state is fast.

8.The rate of chemical reaction is important from environmental point of view as well.

9.The ozone layer in the earth's atmosphere protects the life on the earth from the ultraviolet radiation of the sun. The process of depletion or maintenance of this layer depends upon the rate of production or destruction of ozone molecules.

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 .

Weightlessness In Space Information

 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...

Low And High Tides   What is the value of g Gravitational waves  What is Gravitational Force                                 Do You Know: Low And High Tides INFORMATION:-  what is weightlessness in space                             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 nine...

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...

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.
