The discussion centers on the relationship between bulk modulus and fractional volume change. A change in bulk modulus by 5% does not directly translate to a fractional volume change through simple multiplication or division. Instead, the bulk modulus is a material property that can be influenced by external factors such as temperature, and the fractional volume change is contingent on the specific stress applied to the material. Understanding the context of the materials involved is crucial for accurate calculations.

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?ralden said: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?
