Sorry this might not be great but when the air is cold the molecules are dense which means they are much closer together and hit each other but when they air is hot the molecules aren’t as dense which means they are more spread out. so as the cold air molecules are closer together, more of them could fit inside the balloon but with hot air since the molecules are so far apart not as many can fit in as they take up more as they spread and hit the side of the balloon
What’s the question though
Answer:

Answer: The correct answer is:
Galileo used instruments and experiments to show him what nature was doing, instead of relying on pure logic

Galileo differed from his predecessors because he actually used and developed instruments and method to reliable measure and observe what nature was doing, instead of relying on pure logic.
Answer:
The net force acting on an object is proportional to the acceleration of that object with respect to an inertial frame of reference. The constant of proportionality in this, Newton's second law, is the classical mass of the object.
