The correct answers are:

• The bubbling green concoction rose to the top of the flask...
• Igor raised the massive electrical switch...
• Dr. Stein-Franken laid the ancient spellbook gently...

Rise is an intransitive verb (it doesn't take a direct object), so the concoction rose on its own. Raise is transitive (it needs a direct object), so Igor raised the switch. Therefore, the temperature cannot "raise" on its own; it should have rose. Similarly, lay is a transitive verb requiring an object (he laid the book), while lie is intransitive. The monster should have lain down (or lay down, if using the past tense of lie), not laid down!
