    I have done this experiment at home. That was the reason I asked in the previous video that water expands when temperature is reduced.

    The bottle will brust due to expansion of water and it's anomalous behavior. It's really help me to clear my doubts after watching this video . Thank you video 🙏

    Water is not the only exception - the other exceptions include:-
    Substances like Water from 0°C to 4°C, silver iodide from 80°C to 141°C and Silica below -80°C contract on heating and expands on cooling. The expansion of a substance on cooling at a certain range of temperature is called the Anomalous expansion of that substance.
    Sir your videos really helped a lot.

    The water freezes. When it becomes ice, its volume expands a lot, since the density of ice is much lower than that of water. The bottle will burst because nothing is stronger than the force of expanding water.

  • @sudeepkumardas2981
    @sudeepkumardas2981 3 роки тому +25

    Because when we freeze water at 0degree Celsius,it expand(volume increases) and change into ice due to this expansion bottle gets break..

    Bottle can be blasted because water posses a special type of property that is analmous expansion of water. In this expansion at 4 to 0 degree Celsius ice starts to expand due to which its density become less than the normal water and then blast when it doesn't get sufficient space to expand it

      @kanchan.choudhary0189 29 днів тому +1

      Normally imagine if we have water of temperature 13°C and of we will cool the water it's temperature will decrease. Along with decrease in temperature, it will contract also.
      Suppose it's temperature has reached 4°C then it will start showing anomalous behaviour. I have told that water contracts when we decrease temperature but as you know that it is anomalous behaviour of water, so water will expand instead of contracting when we will decrease temperature from 4°C till 0°C.
      When we heat water, it expands. When we cool water, it contracts. But, water shows totally opposite of its normal behaviour in anomalous behaviour.
      Did you understand? If not then I can explain in more detail
