the fractional change in length,area and volume per unit change in temp. of matters at a given pressure
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.
The coefficient of the thermal expansion of water is equal to .00021. Water expands by 9% of its volume when it freezes.
Superficial expansion is the increase in surface area of 1 meter square area of a solid for rise of temperature, 1kelvin is called the coefficient of surface expansion of material of that solid.

Because liquids have two types of expansions i.e Apparent Expansion and Real 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.
The coefficient of the thermal expansion of water is equal to .00021. Water expands by 9% of its volume when it freezes.
Superficial expansion is the increase in surface area of 1 meter square area of a solid for rise of temperature, 1kelvin is called the coefficient of surface expansion of material of that solid.
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.
define coefficient of surface tension
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
Why aluminium has high thermal expansion coefficient than Copper?"

A binomial coefficient is a coefficient of any of the terms in the expansion of the binomial (x+y)^n.
The coefficient is 6.
yes,according to relation coefficient of linear expansion depends upon original length.
The coefficient is 6.
