You will find your answer in a paper and experiment done at the University of Applied Sciences Jena in Germany. They (M. Schimmelpfening, K. Weber, F Kalb & K.-H. Feller) determined the expansion coefficients of 9 samples of parafin wax with regards to Congealing Point, Needle Penetration and if a crystal transformation had occurred. They included a fully refined macrocrystalline, an intermediate and a plastic microcrystalline. The coefficients range from the micro wax with the higher CP and Pen at .73 X10 (-3) to the 2 phase waxes at .89 x 10(-3) and intermediate at .75. Check out their paper on how they determined these, it's good. Google "Volume expansion of parafins from dip tube measurements"

Explain formula volume expansion coefficient subject expansion of solid?
Formula for the volume Expansion for a solid is αV=1VdVdT and Isotropic materials is αV=3αL.
What is the cubical coefficient of thermal expansion for metals?
Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.
How do you calculate coefficient of linear expansion of copper?
dL/dT = αL*L, where L is the length of the steel, T is temperature, and αL is the linear thermal expansion coefficient which for steel is about 11.0 to 13.0. That is possibly the easiest differential equation in history: (1/L)dL = (αL)dT ln(L) = αLT L = eαLT

What material has the highest coefficient of linear thermal expansion?
nickel
A material has a coefficient of volume expansion of 60×10^-6/degree celsius. What is its coefficient of expansion?
The coefficient of volume expansion is the triple of the linear expansion coefficient. So with a volume expansion coefficient of 60×10^-6/°C, the linear expansion coefficient would be 20×10^-6/°C.
Why liquids have two coefficient of expansion?
Liquids have two coefficients of expansion because they can expand in both volume (volume coefficient of expansion) and in area (area coefficient of expansion) when heated. The volume coefficient of expansion relates to changes in the volume of the liquid, while the area coefficient of expansion relates to changes in the surface area.
What is the relation between the coefficient of linear and superficial and volume expansion respectively?
The coefficient of linear expansion (α) is one-third of the coefficient of superficial expansion (β), and the coefficient of superficial expansion is one-third of the coefficient of volume expansion (γ). This relationship follows from the dimensional analysis of the expansion coefficients in the respective directions.
What is the coefficient of the volume of expansion of turpentine?
The coefficient of volume expansion of turpentine is typically around 9 x 10^-4 per degree Celsius. This coefficient indicates how much the volume of turpentine will increase for a one-degree Celsius increase in temperature.
Does mercury have the highest coefficient of volume expansion known?
Yes, mercury has one of the highest coefficients of volume expansion known among common substances. Its coefficient of volume expansion is approximately 181 x 10^-6 per degree Celsius.
Explain formula volume expansion coefficient subject expansion of solid?
Formula for the volume Expansion for a solid is αV=1VdVdT and Isotropic materials is αV=3αL.
What is the definition of cubical expansion?
Cubical expansion refers to the increase in volume of a substance as it is heated. This expansion can be calculated using the coefficient of cubical expansion, which quantifies how the volume of a material changes with temperature.
What is the volume coefficient of expansion for ice?
The volume coefficient of expansion for ice is approximately 0.090 × 10^-3 per degree Celsius. This means that for every degree Celsius increase in temperature, ice expands by about 0.090 × 10^-3 of its original volume.
Why the coefficient of volume expansion of the water different with coefficient of volume expansion of the ethanol?
The coefficient of volume expansion for a substance is determined by its molecular structure and interactions between its molecules. Water and ethanol have different molecular structures and intermolecular forces, which result in different coefficients of volume expansion. Water has a higher coefficient of volume expansion than ethanol because of its hydrogen bonding and unique properties.
What is meant by cubical expansion?
Cubical expansion refers to the increase in volume of a substance when its temperature increases. It is governed by the coefficient of cubic expansion, which quantifies how much the volume of a substance changes with temperature.
What is the formula for calculating volume change due to heat?
That depends on the exact details. For a gas, the ideal gas law is usually a good approximation: other things being equal, the volume is directly proportional to the absolute temperature (that is, the temperature expressed in kelvin). For a liquid or gas, the expansion is much less than in a gas. You can look up the coefficient of expansion for a specific substance, and then use the definition of the coefficient; that is, the volume change is equal to (volume) times (temperature difference) x (coefficient of volume expansion).
What is the thermal expansion coefficient of ammonia?
The thermal expansion coefficient of ammonia is approximately 0.0045 K^-1 at 20 degrees Celsius. This coefficient represents how much the volume of ammonia will expand per degree of temperature increase.
