What are the three main points of the particle theory of expansion and contraction?
The particle theory of expansion and contraction states that matter is composed of tiny particles that are constantly in motion. When a substance is heated, the particles gain energy and move faster, causing them to spread apart and the substance to expand. Conversely, when a substance is cooled, the particles lose energy, move slower, and come closer together, leading to contraction. This behavior is consistent across solids, liquids, and gases, though the extent of expansion and contraction varies by state and material.
What is the speed of sound in concrete?
Between 3200 and 3600 m/s, the closer together the particles are in a substance are, the faster sound can travel through it. This is why these values are much higher than the 343 m/s, the speed of sound in air.
What happens to air particles as they cool?
The cooler the temperature, the slower the particles move and the closer together they are because they don't need as much room. That accounts for how cooler air is thicker.
What is internal subatomic particles?
Internal subatomic particles refer to the constituents of atoms, primarily protons and neutrons, which are found in the nucleus, and electrons that orbit around the nucleus. Protons and neutrons themselves are made up of quarks, which are held together by the strong force mediated by gluons. Electrons, on the other hand, are considered elementary particles and belong to the lepton family. Together, these particles define the structure and properties of atoms, forming the basis of matter in the universe.
What style of art is the triptych closely associated with?
A triptych is a painting made in three sections that fit together. It can also be three relief carved panels.
What substance is solids?
It is a substance that has a lot of particles that are packed together. The particles can not move becase the solid paticles are to strong.
What is the name of the force that keeps particles of the same substance together?
Cohesion.
Which substance contains particles held together by metalic bonds?
These are metals.
What is a solid's thickness?
It is a substance that has a lot of particles that are packed together. The particles can not move becase the solid paticles are to strong.
What 2 characteristics are needed for a substance to be a solid?
A solid has a definite shape and volume A liquid has the shape of the container and a definite volume A gas has the shape and volume of the container so the two characteristics for the substance to be solid are: a definite shape a definite volume
What is an attraction between particles of the same substance called?
An attraction between particles of the SAME substance is called cohesion.
When two substances are mixed together a magnet can remove particles from a substance.?
A magnet can remove particles from a mixture but not from a chemical compound.
What happens to the particles of a substance when it freeze?
When a substance freezes, its particles slow down and come closer together, forming a more structured and rigid arrangement. This results in the substance transitioning from a liquid state to a solid state.
How does the motion and arrangement of particles is a substance change as the substance freezes?
As a substance freezes, the particles slow down and move closer together, forming a more ordered arrangement. This results in a decrease in the substance's volume and a transition from a liquid to a solid state.
What is it called when the particles are tightly packed together?
its not a substance its a state of matter which is the solid the solid's particles are packed tightly together glad 2 help !! :)
What is added to water to bring the small dirt particles together?
This substance is called flocculant.
How does particle speed relate to the distance between particles?
Particle speed is not directly related to the distance between particles. The speed of individual particles in a substance is determined by factors like temperature and pressure. However, the average speed of particles in a substance can affect the distance between particles indirectly by influencing the pressure exerted by the substance.
