Basics of thermodynamics
... A wall that constrains an extensive parameter of a system to a definite value is said to be "restrictive" wrt that parameter, whereas a wall that allows the parameter to vary freely is "non-restrictive" wrt that parameter. Thus a wall that is impermeable to a chemical species is restrictive for the ...

Review of classical thermodynamics
... 1st Law – conservation of energy in a thermodynamic process A state function, called the internal energy, exists for any physical system – and the change in the internal energy during any process is the sum of work done on/by the system and heat transferred to/from the system. ΔU = q – w or in diff ...

... Energy transferred as heat from the burner to the water. Internal energy of the water is increased until the water reaches its boiling point and changes phase. Volume of steam increases; expansion provides a force that expands the balloon and does work on the atmosphere (by pushing it back). o Steam ...
