FREE Expert Solution

We are asked to identify which of the following phase changes must heat be added to overcome intermolecular forces.


Recall that a phase diagram shows the transition of matter between solid, liquid, and gas phases as temperature and pressure changes.


In a phase diagram, the different phases can be identified by their location:

• Solid: can be found at high pressure and low temperature

• Liquid: can be found between the solid and gas regions

• Gas: can be found at low pressure and high temperature
