The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
The density of the solid substance remains unchanged when it is cut in half. The mass and volume are both halved, which means the ratio of mass to volume, i.e., density, stays the same.
If the density of a solid substance is greater than that of the liquid it is placed in, the solid substance will sink to the bottom of the liquid. This occurs because objects with higher density will displace an equal volume of the lower density liquid, causing the solid to sink.
If the density of a solid substance is more than that of a liquid, the solid substance will sink in the liquid. This is because objects with higher density will displace a volume of liquid that has a lower density, causing the solid to sink to the bottom.
When a particle gets hot, its internal energy increases, causing its atoms to vibrate more rapidly. This increased vibration results in the particle expanding in volume, decreasing in density, and possibly changing phases (e.g., from solid to liquid).
In general, the particle size remains the same during a physical change. The arrangement or organization of the particles may change, but the individual particles themselves do not break down or change in size.
Use particle theory of matter to describe what happens to the density of a substance when it cools down
i. dont.know
Particle Movement decreases.
Nothing happens if the volume is also allowed to increase.
You die
The density will remain the same.
It floats.
The density of a substance remains constant regardless of the amount of the substance. Density is an intrinsic property of a material and is determined by its mass and volume. Increasing the amount of substance will only change the mass and volume proportionally, thus keeping the density constant.
If density is lower than water it will float (unless it is soluble and dissolves)

If you add more of the same substance to an object, the density of the object will increase. Density is calculated by dividing the mass of an object by its volume, so as you add more substance, the mass increases but the volume does not increase proportionally, resulting in a higher density.
When you keep the volume constant and increase the mass of a substance, the density of the substance will also increase. Density is calculated as mass divided by volume, so if volume stays the same and mass increases, density will increase as well.
