Consider statements (A) and (B) given below:
A. Thermodynamics deals with the process of conversion of heat into work only.
B. Heat given to a system and work done by the system are state variables in thermodynamics.
Choose the correct option.
Statement (A) is correct but statement (B) is incorrect
Statement (A) is incorrect but statement (B) is correct
Both statements are correct
Both statements are incorrect

Solution:

Statement A is incorrect because thermodynamics also deals with other energy conversions. Statement B is incorrect because heat and work are path functions, not state variables.
