Correct answer: B. physical processes
- A. chemical processes
- B. physical processes
- C. biochemical processess
- D. endothermic processes
Explanation
Sublimation, vaporization, melting, and photosynthesis are all examples of different physical processes.Sublimation refers to the process where a substance transitions directly from the solid phase to the gas phase without passing through the liquid phase.Vaporization is the process of a substance changing from a liquid phase to a gas phase.Melting is the process where a substance changes from a solid phase to a liquid phase.These processes involve changes in the physical state of matter without altering the chemical composition of the substances involved.

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.
