What is superficial expansion?
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.
A material has a coefficient of volume expansion of 60×10^-6/degree celsius. What is its coefficient of expansion?
120×10^-6
Why liquids have two coefficient of expansion?
Because liquids have two types of expansions i.e Apparent Expansion and Real Expansion
Why is it necessary to know the coefficient of linear expansion of solids?
By knowing the coefficient of linear expansion of solids, you can determine how a solid reacts to temperature. Everything reacts to thermal expansion. For instance, a concrete bridge expands when hot, and with the formula for expansion and the coefficient for it, you know just how much that concrete expands and you can plan and build accordingly. That saves lives.
Water expands as it freezes can you define a coefficient of volume expansion for the freezing force?
The coefficient of the thermal expansion of water is equal to .00021. Water expands by 9% of its volume when it freezes.

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 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 the coefficient of the x2y term in the expansion of (x 2y)3?
