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.

Why liquids have two coefficient of expansion?
Because liquids have two types of expansions i.e Apparent Expansion and Real Expansion
Do all solids expand by the same amount when heated through same temperature?
no , all solids do not expand by the same amount when heated through same temperature. it depends upon the coefficient of its linear expansion. We define avergae co-efficient of linear expansion in the temperature range deltaT as α=(1/L)(ΔL/ΔT) where L is initial length of the solid at the temperature T.. It varies from material to material , higher the value of alpha , it expands more..
Give examples of expansion of solids?
All solids expand when they are heated. Examples include concrete slabs having spacers between them to accommodate expansion, and balloons expand with air being pumped into them and contract when air is let out.
Liquids usually have higher volume coefficients of expansion than solids do?
that is TRUE
What is a sentence for thermal expansion?
Thermal expansion is the dimensional changes exhibits by solids, liquids, and gases for changes in temperature while pressure is held constant.
Why liquids have two coefficient of expansion?
Because liquids have two types of expansions i.e Apparent Expansion and Real Expansion
Why are there laws only for gases and not for solids or liquids?
There are laws for solids and liquids, too. For instance solids have a coeffient of linear expansion and liquids (and gasses) have a viscosity. Many others.
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 the thermal coefficient of volume expansion for a solid?
That depends entirely on the solid. Some solids have larger coefficients, some smaller.

Why expansion of water is more than expansion of solids?
The inter atomic force is comparatively less in case of liquid

How linear motion of shale shaker is obtained while circulating and drilling to remove drill cuttings?
Linear motion shale shaker separates solids from liquids by utilizing a vibrating basket, that might be outfitted with specially-designed and -sized screens in oilfield drilling mud solids control system. Shaker is regarded as primarily essential solids control equipment of the most necessary tool for removing drilled solids. These units take away the majority of drilled solids generated through the widespread drilling course of action. Shale shakers normally create involving 5 to more than eight G-forces of energy for removing solids in the mud plan.

What is it called when solids are heated?
Thermal expansion in accordance with the first law of thermodynamics.
Give examples of expansion of solids?
All solids expand when they are heated. Examples include concrete slabs having spacers between them to accommodate expansion, and balloons expand with air being pumped into them and contract when air is let out.
Expansion of solids as they become warmer?
Solids comprise of atoms. As temperature increases, the atoms vibrate and move further from each other. The effect makes solids to expand in all directions.
