What factors influence the magnitude of the enthalpy change during phase transformations?

Options

  1. AThe strength of intermolecular interactions
  2. BThe color of the substance
  3. CThe size of the substance
  4. DThe shape of the substance

Correct answer

A. The strength of intermolecular interactions

Step-by-step solution

The magnitude of the enthalpy change during phase transformations depends on the strength of the intermolecular interactions in the substance undergoing the phase transformation. Substances with stronger intermolecular interactions typically require more heat to change phase.
