you make vei nice and short to the point knowledge loaded videos... #keep it up.. as a viewer of your bytes series i want to suggest you to make videos on India's Intelligence Agencies, their formation and secret missions which had safeguard our nation from external and internal threats. lets honour those who worked 24*7 365 days without being noticed and does not even gain fame from their incredible service towards our nation. Thank you.
  1. . Open System- can transfer mass and energy between system and surrounding. Closed System- can transfer only energy. Isolated System-can transfer neither energy . nor matter.


  2. Broad divisions of systems 1) Homogenous system-When the system is completely uniform throughout Example-a gas box, a pure crystal 2) Heterogeneous system- will have Two or more phases Eg liquid and its vapour


  3. Types of walls to bound a system Rigid and Non Rigid Walls * Permeable wall and Impermeable Walls Adiabatic Walls and Non Adiabatic Walls


  4. Thermodynamic Properties Extensive Properties- Its value is sum of values of the parts of the system. Example-Mass


  5. Intensive Property-Value doesn't depend on size of system.


  6. Why we need Thermodnamic properties? We define them to compare between two thermodynamic systems. f they are same for two different systems.They are essentially same!
