Answer:
The answer is False
Step-by-step explanation:
If you want a visual representation, take water. When its left at room temperature the molecules are moving but not very fast. If you bring that water to a boil, the molecules move a lot faster and get closes together. If you were to freeze that water inside a closed container you would see the water inside expand because the molecules grow further apart.
To answer the question, while the molecules do move faster, they do not move further apart.
