SYSTEM SURROUNDINGS

• System: quantity of mater under analysis
• Surroundings: everything external to the system
• System boundary: physically separates the above two
08/24/26
27
• Thermodynamic version of a free-body diagram
• Identifies all mass and energy transfers across a system boundary
Note on System Boundary
• We only care about interactions that occur across the boundary
• System 1: Water within the rigid tank
• Heat transfer from the copper “crosses”
the boundary
• System 2: Water within the rigid tank
and copper mass
• Heat transfer between copper/water
is completely internal to the “system”
• Does not appear in EFD
