    4. HI SIR, I bought Physics Galaxy recently. I m happy as the book is awesome. But wanted to ask if there is elasticity, surface tension and viscosity in the book as I did not find it in my copy[ only asking], if no, would u tell me when will the chap. be added ?? But once again all ur books are awesome, they give such conceptual clarity and so many good questions are there in it ... thanks a lot for ur time, dedication and books :)

    7 years ago by Abhishek Jaswal
    Ans 1 ->
    fluid is there in volume 2 and it is available in market... viscosity, surface tension and elasticity is there in volume 3..

    Ans 1 ->
    you don't need to ask same query again... it distracts other viewers... If you are using a resource on internet, you must take care of other users otherwise you will regret later in some case... following internet etiquette is must for all...

    25. what do you mean by compressibility factor.. what is the compressibility factor of water?
    9 years ago by sezal
    Ans 1 ->
    compressibility is taken as reciprocal of bulk modulus of medium... which gives an idea about how compressible the material is... Qualitatively it is opposite to elasticity...

    change in lenth by original lenth
    9 years ago by d.a.choudary
    Ans 2 ->
    Pl watch videos under 'PG video lectures' tab of the section 'Properties of Matter' under the topic 'Elasticity' in sequence from start to get it in detail from scratch...
