The SI unit for work is _.
Correct answer: B. Joule
- A. Newtons
- B. Joule
- C. Newton/metre
- D. All of these
Explanation
The S.I unit of work is joule, work is also a form in which energy is transferred from one system to another. It is defined as the product of force and distance i.e. W = F x dS It is a fact, and it should be memorized.

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.
