The change in diameter (∆L) is given by the formula ∆L = α∆T L, where α is the coefficient of linear expansion, ∆T is the change in temperature, and L is the original length. Plugging in the values, we get:
2.3x10-5m = α * 75℃ * 1.8x10-2m
Solving this equation gives α = 1.29x10-5 per degree Celsius.

What is the relationship of coefficient linear expansion to actual expansion?
The coefficient of linear expansion is a constant value that quantifies how much a material expands per degree Celsius increase in temperature. The actual expansion of an object can be calculated by multiplying the coefficient of linear expansion by the original length of the object and the temperature change.
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 the thermal expansion coefficient for JET A1?
The thermal expansion coefficient for Jet A1 fuel is typically around 0.0008 per degree Celsius. This means that for every degree increase in temperature, the fuel will expand by about 0.08% of its original volume.
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.
What is the thermal expansion coefficient for motor spirit?
The thermal expansion coefficient for motor spirit, also known as gasoline, is approximately 0.00096 per degree Celsius. This means that for every degree Celsius increase in temperature, gasoline will expand by 0.00096 of its original volume.
Does the coefficient of linear expansion depends upon length?
yes,according to relation coefficient of linear expansion depends upon original length.

The actual expansion of an object can be calculated by multiplying the coefficient of linear expansion by the original length of the object and the temperature change.
Do all solids expand on heating?
Yes, they do. The phenomenon is called thermal expansion. Every substance has a "coefficient of expansion" figured out via experiment. The coefficient is used in the following way. change in length = original length * change in Temperature (K) * coefficient of linear expansion change in volume = original volume * change in Temperature (K) * coefficient of volume expansion The coefficient of volume expansion is three times the coefficient of linear expansion. The unit for the coefficient is "per degree" (this makes more sense when you use it in an equation)
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 the Coefficient of thermal expansion for oxygen?
The coefficient of thermal expansion for oxygen is approximately 0.0012 per degree Celsius. This means that for every one degree Celsius increase in temperature, oxygen will expand by 0.12% of its original volume.
The expansion of a binomial that involves a coefficient found by combinations. The expansion will contain the same number of terms as the exponent of the original binomial. For each term the exponents?
Not true. The expansion will have one more term.

What is a water droplet in a cloud that becomes rain when its diameter increases to how many times its original size?
A water droplet in a cloud becomes rain when its diameter increases to around 50 times its original size. This process is known as coalescence, where smaller droplets merge together to form larger droplets, eventually becoming heavy enough to fall as rain.
Does the coefficient of linear expansion depend upon length describe?
The coefficient of linear expansion is a constant for a given material and doesn't depend on the length of the material. It represents the fractional change in length per degree Celsius of temperature change.
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
