What is the unit of coefficient of linear expansion of a solid?

The real expansion of any liquid depends on the expansion of the vessel in which it is kept.

Among iron, invar and copper, which one has the least coefficient of linear expansion?

State whether the following statement is true or false:
“The constituent particles of a material change position during conduction of heat through it.”

Which quantities remain fixed in the definition of volume expansion co-efficient of a gas? Name a non-metal, which is a good conductor of heat. 

What is meant by ‘linear expansion coefficient of copper’ is $17\times {10}^{-6}/°\mathrm{C}$? Why does the value remain the same even in kelvin scale?
