5. ______ is required to change a substance from a solid to a liquid or from a liquid to a gas. blank

Explanation:

Question 1

In the states of matter, solids have particles packed tightly, only vibrating. So the word from the bank is "solids".

The process of a liquid turning to a solid is freezing (e.g., water to ice). So the term is "freezing".

Sublimation is when a solid turns directly to gas (like dry ice to CO₂ gas). So the process is "sublimation".

Answer:

solids
