In thermodynamics, heat and work are :

Options

  1. APath functions
  2. BIntensive thermodynamic state variables
  3. CExtensive thermodynamic state variables
  4. DPoint functions

Correct answer

A. Path functions

Step-by-step solution

Heat and work are treated as path functions in thermodynamics. Δ Q = Δ U + Δ W Since work done by gas depends on type of process i.e. path and Δ U depends just on initial and final states, so Δ Q i.e. heat, also has to depend on process is path.
