Demonstration of Adiabatic Process
If there is no exchange of heat between system and surrounding then it is called adiabatic process for this to be happen the walls of the system should be 100% heat insulator or the process should be very fast or both
Here there is smoke trapped in partially filled water , if we sudden increase pressure , heat generated and so moisture converts into water vapour so it becomes transparent and if we suddenly release the pressure the water vapour condenses to microscopical droplets so it becomes translucent
You can also see optical property of the gaseous mixture with smoke particle changes on pressure
