Choose the correct answer.
A thermodynamic state function is a quantity :

  1. used to determine heat chages
  2. whose value is independent of path
  3. used to determine pressure volume work
  4. whose value depends on temperature only

A
used to determine heat chages
B
whose value is independent of path
C
whose value depends on temperature only
D
used to determine pressure volume work
Solution
Verified by Toppr

The correct option is B whose value is independent of path
A thermodynamic state function is a quantity whose value is independent of path. Thus, enthalpy is a state function.
Its value depends on iniital and final states and is independatn of path followed.
