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.
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.
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 expansion of water is more than expansion of solids?
The inter atomic force is comparatively less in case of liquid
How engineers prevent the expansion of solids from damaging structure?
[object Object]
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.

What is it called when solids are heated?
Thermal expansion in accordance with the first law of thermodynamics.

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.
Liquids usually have higher volume coefficients of expansion than solids do?
that is TRUE

A thermometer works on the principle that a rise in temperature causes?
A rise in temp causes the expansion of the mercury or alcohol present in the tube.The graduation is done in such a way that the amount of expansion gives the temp.
