Usually. A2: Not, not usually. Something with high thermal efficiency usually has "pockets" of gas in it, say, closed-cell polyurethane foam. The total dielectric strength, therefore, is not much better than using the same volume of gas or air used to blow it.
It wasn't the engine being steam-powered as such, nor especially in  America; but the development of the railways allowed people and  goods to be transported efficiently and reasonably rapidly over  long distances. This was the same as in the UK, in Europe, etc.
Expansion and contraction can cause things to crack, as in the  weathering of rock. They can cause a bi-metal strip to bend and  straighten, which phenomenon is used in some thermostats. Expansion  can cause the roadway of a bridge to buckle, so gaps have to be  left. Obviously they cause the...
