Answer
Speeds up
Explanation
When a substance changes from a liquid to a gas, the particles gain energy and move more rapidly. This increase in energy causes the particles to overcome the intermolecular forces holding them together in the liquid state, allowing them to move freely and spread out as a gas. Therefore, the particle motion speeds up during this phase transition.
