When gases are mixed, the internal energy will remain conserved. When external energy provides heat energy there may be temperature variation leading to internal energy change and/or volume variation spending/gaving work/energy.

1.	When gases are mixed, the internal energy will remain conserved. When external energy provides heat energy there may be temperature variation leading to internal energy change and/or volume variation spending/gaving work/energy. The change is internal energy is independent of the path followed, while work and heat energy depends on the path followed.
