What else can I help you with?
The more particles a substance has at a given temperature?
the more thermal energy it has
The More particles a substance has at a given point the higher its temperature?
The more thermal energy it has
How do you know that particles in a gas have more energy than particles of same substance as a liquid or a solid?
We know that for any given substance, and at a given pressure, the gas phase exists at a higher temperature than the liquid phase, which exists at a higher temperature than the solid phase. And temperature measures heat energy per molecule or atom, hence, gas particles have more energy than particles of the same substance in their liquid or solid phase.
What is determined by the distance between the particles in a given substance?
Density.
How to calculate number density in a given substance?
To calculate number density in a substance, you divide the number of particles in the substance by the volume of the substance. This gives you the number of particles per unit volume.
Is the density higher or lower when the particles are closer in a substance?
The density is higher when the particles are closer together in a substance because there is more mass packed into a given volume. This leads to a higher mass per unit volume, which is the definition of density.
Why do substance expand when heat energy is added to them?
Heat is a measurement of the amount of motion (or kinetic energy) of the particles of which a given substance is composed. In a solid, this motion is just a vibration, since the particles remain in place. When particles vibrate more, they will take up more space. In a gas, the particles move independently of each other, and if they move faster, they will exert more pressure and thus will tend to expand.
What happens to particles when thermal energy is given to them?
When thermal energy is given to particles, they gain kinetic energy and begin to vibrate or move more rapidly. This increase in movement causes the particles to spread out and the substance to expand, leading to a rise in temperature.
When particles in a substance move more in the gaseous state that given substance has greater what than the other states?
When particles in a substance move more in the gaseous state, that substance has greater kinetic energy compared to its solid and liquid states. This increased movement allows gas particles to spread out and fill their container, resulting in lower density and higher compressibility. Consequently, gases exhibit different physical properties than solids and liquids, primarily due to the greater freedom of movement of their particles.
What best defines density?
Density is a measure of how much mass is contained in a given volume of a substance. It is typically calculated by dividing the mass of an object by its volume. The higher the density, the more compact the particles are within the substance.
Avogadro's is useful for what?
It is the number of particles in one mole of a given substance. used to convert units.
What happes to particles in a substance when the substance's temperature increases?
As the substance's temperature increases, the particles within the substance gain energy and begin to move faster. This increased movement causes the particles to occupy more space as they spread out, leading to expansion of the substance. If the temperature increase is sufficient, the substance may change state from solid to liquid, or from liquid to gas.
