Mark the incorrect statement:
Correct answer: B. B
- A. A
- B. B
- C. C
- D. D
Explanation
The term system is used for anything (materials) under test in the laboratory, or under consideration in the classroom for the purpose of argument. We can say that any portion of the universe which is under study is called a system and the remaining portion of the universe is known as its surroundings. The reaction between Zn and CuSO4 solution can be called a system under observation. The flask, the air, etc. are the surroundings.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
