    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.

    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 water bottle burst becoz as the temp. Goes down the expansion of water occurs[ after 4 degrees Celsius ] .due to this anomalus behaviour this happened
    You explained amazingly. I watched almost 4 to 5 videos but didn't understand as perfect as you taught ...❤❤thanks to you

    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.

  • @shachisomya4270
    @shachisomya4270 4 роки тому +7

    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

  • @sudeepkumardas2981

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