water vs temperature

Water  vs  Temperature

Hello, friends here i'm going to tell you, how the behavior of water changes with respect to temperature .
          
We have seen that every liquid expand in volume on heating  but there is another situation in case of water  because water has HYDROGEN BONDING  and have DIPOLE MOMENT.

now,in the case of water, when water is heated from 0 to 4 degree Celsius it's  volume decreases  and after 4 degree Celsius it's volume start to increase.

            Due to this phenomenon, in our every day life we can see the natural secrets.
 Now using this phenomenon ,
                                             i'm going to tell you a number of natural effects.

Density of water

                    since we know that at 4 degree celsius the volume of water is minimum,it means that at 4 degree celsius the density of definite mass of the water is maximum (1.000 gram per cm cube).
 The graph is shown below.............
 it is clear from the graph that from 0 to 4 degree celsius density of water increases and  max at 4 degree celsius, on further increasing the temperature  volume increases and so density decreases.

 due to this fact the volume of ice cube is greater than water liquid.

therefore the density of water is greater than ice. 

why the fishes  not die on freezing the lake


 In winter seasons air temp decreases to 0 or minus  degree celsius  due to this water start to freeze of ponds. Now slowly slowly cold water from surface move to bottom of pond(cold water is heavier than hot water) this process is continued till the temperature is falls to 4 degree celsius of whole pond.


                   when the temperature of water surface start to fall from 4 degree celcius then the density of water start to decrease. 
IF ANY SUBSTANCE HAS LESS DENSITY THAN WATER  THEN IT WILL FLOW ON SURFACE OF WATER.
 Now the water is changing into ice and due to less density the ice will flow on the surface
 SINCE WE KNOW THAT ICE IS INSULATOR FOR HEAT 
therefore coldness from air could not come into water because ice is on surface of water
hence the water under ice is in liquid state
  Hence fishes do not die in winter season while the lake or pond is freezed.

 In winter rocks crack itself,why???????????

Due to the rain water enters in the rocks from holes and small cracks and in cold season when water freezes then due to expansion in volume of water  rocks crack itself.


This phenomenon works behind the these facts also............

  • Cracking of water pipes in winter seasons
  • cracking of plants nerve in winter season.

Bernoulli's Theorem

Floating of Ping-Pong Ball on  water jet & air jet The principal  behind floating of a ping -pong ball is based on  BERNOULLI'S THEOREM now i am  going to tell you the whole principal behind this phenomenon. pin-pong ball placing on air jet First to understand this phenomenon, we should to look upon BERNOULLI'S THEOREM BERNOULLI'S THEOREM        This theorem is like energy conservation principle.   "When a non-compressible and non-viscous Liquid or Gas flow like linear current motion, then  at any point of it's path the TOTAL ENERGY (sum of pressure energy, kinetic energy and potential energy) of liquid or gas  remains constant."                                      It is the BERNOULLI'S THEOREM now the the conclusion comes out that            "the side where the velocit...

Beautiful phenomenon based on surface tension

Beautiful phenomenon based on surface tension Hello friends, here i'm going to tell you some  more  special and beautiful phenomenon based on surface tension. The first is............. 1.Formation of Lead Shots (MARBLES) For making marbles, we take the melted glass in liquid form. Now from a certain height melted glass is threw into  a big water tank as a fountain. During fall of glass liquid due to surface tension the melted glass acquire minimum surface area and turns into spherical marbles. Reaching to the water tank it converts into solid marbles. By this process the beautiful & colorful marbles  are formed,in case of big drops it is affected by gravity and it becomes some flat. NOW BEAUTIFUL  MARBLES ARE READY 2.Spraying results in coldness When we spray water on skin or on anyone then we feel coldness why?? do you know?? When we spray water then it converts into numerous small drops due to this the surface ar...
