Q. 11.11 The coefficient of volume expansion of glycerine is What is the fractional change in its density for a rise in temperature?
Coefficient of volume expansion of glycerine is
Let initial volume and mass of a certain amount of glycerine be V and m respectively.
Initial density is
Change in volume for a 30 oC rise in temperature will be
Final Density is
Fractional Change in density is
The negative sign signifies with an increase in temperature density will decrease.
