Vedclass · Answer

(A) In thermodynamics,variables used to describe the state of a system are called state variables or thermodynamic variables.$1$. Extensive variables: These are properties whose values depend on the size or the extent of the system (i.e.,the amount of matter present). Examples include mass,volume,internal energy,and entropy.$2$. Intensive variables: These are properties whose values are independent of the size or the extent of the system. Examples include temperature,pressure,and density.These variables are fundamental in defining the macroscopic state of a thermodynamic system.

What are extensive variables and what are intensive variables? What are these variables?
