What are the phase change processes taking place when a substance is in equilibrium between liquid and gas phases? a. melting and boiling b. expanding and contracting c. evaporating and condensing d. freezing and thawing

 C. Evaporating and condensing

Explanation:  Phase change process id the process in which the phase of one substance is transforming into the another.

These chemical process of transformation can takes place under dynamic equilibrium in which conversion of one phase is in equilibrium with the another one.

In this liquid phase is transforming into the gas phase which is known as Evaporation and gaseous phase is converting back into the liquid phase which is known as Condensation.

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

its first and third is your answer i did the qustion the fourth isnt right
