When using the particle model of matter to describe what happens to the density of a substance when it cools?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
What is determined by the number of particles of a substance in a solution?
Heat is the speed of the particles the higher the speed the higher the heat. Density or state of matter is the distance between the particles the closer the particles the higher the density, the density of the particles determines the state of matter here they are from most dense to least dense; Solid, Liquid, Gas, and Plasma. the temperature (heat) of a substance can also determine the state of matter a substance is with higher heat at lower densities. PS the density/state list does not apply to water. PS Quantum state is not currently an official state yet, it would be the most dense and at the lowest temperature.
What is the measure of the speed of particles in a substance?
When we heat a substance, the energy absorbed is converted into kinetic energy of the particles in it. The faster the particles in it vibrate, move, collide, etc. the higher the temperatureof a substance.So the expected answer is Temperature
Why do liquids have lower density than solid?
Not all liquids have lower densities than all solids. Low density solids frequently contain air or other gasses as part of their makeup (cok, Styrofoam, etc)
What are two ways to compare the density of a unknown substance?
One way is using the formula D=m/v. Or you could get some water and put the substance inside the water and see if the density is lower or higher.

What does a substance gain or lose when its temperature changes?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
What has a higher density liquids or gases?
If you think of density in terms of particles this becomes easier to remember. In which would the particles be closer together? A liquid, so the liquid is denser.
How does upthrust vary liquid of different densities?
if a substance has more particles in a smaller space (higher density), then the substance can be less easily displaced and has a higher upthrust
What is the movement of particles from regions of lower density to regions of higher density?
The movement so described is called diffusion. When particles of regions of higher density move to regions of lower density, they are said to diffuse.
What use of toluene displacement method?
This method is used for the determination of True density of the particles i.e Grains, any liquid substance etc. True density refers the density of the material with compaction. The value is always higher than Bulk density.
What is the main idea of density?
Density is a measure of how much mass is contained in a given volume of a substance. It indicates how closely packed the particles are in a material. Objects with higher density have more mass packed into a smaller volume than objects with lower density.
As you get higher in the atmosphere does the particles get closer together or farther apart?
the particles get closer together because my class just talked about that stuff!!
The more particles a substance has as a given in what?
the higher its tempeture
Why does mass and volume affect density?
The density of a substance is its mass divided by its volume. So for the same volume the higher the mass, the higher the density.
Which type of planet will have a higher overall density?
planets that are closer to the sun usually will have higher density compared to ones further from the sun.
