Step 1
Step 1: Understand the concept of phase changes Phase changes refer to the transformation of a substance from one physical state to another, such as solid to liquid (melting), liquid to gas (vaporization), gas to liquid (condensation), and liquid to solid Show more…

Which statement best explains what is occurring during a phase change from liquid to gas? During a phase change the temperature stays constant as heat energy is added because the energy is used to overcome intermolecular forces and allow molecules to move further apart. During a phase change the temperature increases because the molecules are breaking down into their individual protons, neutrons, and electrons. During a phase change the temperature increases because the molecules are getting larger. During a phase change the temperature stays constant as heat energy is added because the energy is used to perform chemical reactions breaking the bonds between individual atoms. During a phase change the temperature increases because the molecules are getting hotter.
