Transformers can be filled with various types of Refined Mineral Oil. That coefficient is something you would find in specifications of the supplier.
Commonly, it is .08% per degree Centigrade.

What is Coefficient of cubical expansion of heavy water?
The coefficient of thermal expansion depends on the temperature and pressure. It a pressure of 1 atmosphere the coefficient of thermal expansion are:at 4 deg C : –0.1321 at 20 deg C : 0.1212 at 50 deg C : 0.4280 at 100 deg C: 0.7454.
Why should the coefficient of thermal expansion of a refractory metal be the lowest?
refractory metals have high melting points and are used in extremely hot environments; if expansion coefficient is lower this prevents high stresses that can develop due to thermal gradients during the high heat up. It helps to have high thermal conductivity as well
Why does the thermometer fill with mercury?
It's used in thermometers because it has high coefficient of expansion. also it's the only metal in a liquid state.
Will the volume change in the container?
Yes, depending on what material it's made of, it would have a different coefficient of thermal expansion. Materials expand with heat.
What is the thermal expansion coefficient of ammonia gas at standard temperature and pressure?
Most of the time when you encounter argon and nitrogen they will be gasses. Until you get up to high pressures, they will both behave more or less like ideal gasses. For an ideal gas, the volumetric thermal expansivity (i.e. relative change in volume due to temperature change) is: ßp = 1/T where p denotes a constant pressure process. The coefficient of linear expansion can be calculated from this to get: α ≈ ßp/3 For liquids, the value has to be measured because it certainly isn't an ideal gas when it is liquid! For liquid argon, the coefficient of thermal expansion is reported to be 0.01113 1/°C. For liquid nitrogen, the coefficient of thermal expansion is reported to be 0.00753 1/°C Note that you have to get down to cryogenic temperatures to liquefy argon and nitrogen and it tends to be under pressure when stored in a closed vessel.
What is the expansion coefficient of edible oil?
I think 0.000621
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.
What is coefficient of superficial expansion?
The coefficient of superficial expansion refers to the ratio of change in area to an increase in its temperature. It measures the expansion of a Laminar surface.

What is a binomial coefficient?
A binomial coefficient is a coefficient of any of the terms in the expansion of the binomial (x+y)^n.
What is oil transformer?
Transformer oil is pure insulating oil.
What is the coefficient of the x2y term in the expansion of (x 2y)3?
The coefficient is 6.
Does the coefficient of linear expansion depends upon length?
yes,according to relation coefficient of linear expansion depends upon original length.
What is the coefficient of the x2y term in the expansion of (x plus 2y)3?
The coefficient is 6.
