### I Is a quasi-static but irreversible process possible?

A reversible process doesn't increase entropy and thus cannot exist in the real world (although we can come arbitrarily close). Every real process...

### I Factors that determine the coefficient of linear expansion

Oh, definitely. My link shows only the trend for elements, and even then the correlation isn't absolute. With ferritic alloys, you're going to get...

### I Factors that determine the coefficient of linear expansion

Agreed. Since thermal expansion in ceramics and metals is primarily dependent on the shape of the atomic pair potential and its depth, the...
