Question

In thermodynamics, heat and work are : (A) Path functions (B) Intensive thermodynamic state variables (C) Extensive thermodynamic state variables (D) Point functions Official Ans. by NTA

Tardigrade Admin · Accepted Answer

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.

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

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.
