Very fast chemical reactions in an open chamber: volume exchange, no heat exchange
A semipermeable membrane: constant volume, particle number changes \(\Rightarrow\) Osmosis
System exchanges radiation energy with its surrounding area: The earth
This large amount of possible thermodynamic contacts each with a special name (often several different names for the same contact) confuses many students and scientists which are not strongly involved in thermodynamics. The transformation of thermodynamic contacts will therefor be discussed in detail in the following.
