What is meant by an adiabatic wall?​

Answer 1

$\huge\underline{\underline\mathtt{Answer:-}}$

An adiabatic wall is a wall or partition separating two systems that does not allow any exchange of heat between them. That is, it is a perfect thermal insulator. The systems separated by an adiabatic wall are said to be thermally isolated, e.g. partitions made from the materials such as plastic, glass wool, wood, etc.

[$\bf\large\underline\green{Note-}$: The adiabatic wall is generally shown with slanting lines as a thick cross-shaded region]

Answer 2

In thermodynamics, an adiabatic wall b/w two thermodynamic systems does not allow heat or matter to pass across it . In theoretical investigations it is sometimes assumed that one of the two systems is the surrounding of the other. ......
