Physics - Heat & Thermo Question with Solution | TestHub

Heat and work are treated as path functions in thermodynamics.

$\mathrm{\Delta }Q=\mathrm{\Delta }U+\mathrm{\Delta }W$

Since work done by gas depends on type of process i.e. path and $\mathrm{\Delta }U$ depends just on initial and final states, so $\mathrm{\Delta }Q$ i.e. heat, also has to depend on process is path.
