1. If two objects have the same mass, but object A is much bigger than object B, what can you say about the particles in the two objects?

Question

Objects A and B have particles that are equally closely packed.
You cannot say anything about the particles.
Object A has particles that are more closely packed.
Object A has particles that are less closely packed.

Answer 1

If two objects have the same mass but object A is much bigger than object B, you can conclude that object A has particles that are less closely packed.

This is because the mass of an object is the product of its volume and its density. If both objects have the same mass but one is significantly larger, then object A must have a lower density compared to object B, indicating that its particles are less closely packed.
