Relationship of bulk modulus and fractional volume change

  1. Feb 29, 2016 #1
    So my question is, if the bulk modulus change by 5%, what is the fractional volume change value? is it times 0.05 or divided by 0.05? or the fractional volume change still the same?

    I can't make sense of the question. Bulk modulus is a property of the substance. You could change its bulk modulus by, say, heating it, but how is that connected with a fractional change in the volune of a sample?

    Perhaps you have samples of two substances with different bulk moduli, and you know the fractional volume change in one due to some stress, and wish to deduce the fractional change in volume of the other sample subjected to the same stress?
