Density tells us how much matter is packed into a measured volume. That means:
Density=
Mass
______
Volume
So that means the more dense an object is, the more particles in them are compressed together (heavier).

Not necessarily. Density is mass per volume, so more mass would mean more density only if the volume did not increase proportionally as well.
If an object is more dense, it will sink in a fluid that is less dense than itself and float in a fluid that is more dense than itself. Density is a measure of how much mass is contained in a given volume, so a more dense object will have more mass packed into the same space compared to a less dense object.
No. A stone has much higher density than a styrofoam mattress, but much less mass.
A cool object is generally more dense than a hot object. As a hot object heats up, its particles have more energy and move around more, causing the object to expand and become less dense. On the other hand, a cool object's particles have less energy and are more closely packed together, making it more dense.
An object that is more dense than the liquid it is floating in will sink because of buoyancy. The buoyant force acting on an object is equal to the weight of the fluid displaced by the object. If the object is more dense than the liquid, the weight of the object is greater than the buoyant force, causing it to sink.
When something is more dense than water, it will sink. This is because the upward buoyant force exerted by the water is not enough to overpower the gravitational force pulling the object downward.
A cold object is usually more dense than a hot object because colder temperatures cause particles to move less and come closer together, increasing the object's density. Conversely, in a hot object, particles move faster and spread out, decreasing its density.
When light enters a more dense object, such as water or glass, its speed decreases and it bends, a phenomenon known as refraction. The degree of bending depends on the difference in densities between the two mediums. Ultimately, the light may continue through the object, reflect off its surface, or be absorbed by it.
