Answer #1

Metals get changed during heating and cooling and the changes occurred  during both expansion and contraction are considered to be reversible changes because during heating metal expands but during cooling them they contract for i.e. Blacksmith heat the rim of bullock cart to fit it into the wheel and then it kept for cooling so it's reversible ,railway track get gap during day time summer due to expansion.
