What else can I help you with?
Solid particles remain completely still true or fals?
False. While solid particles maintain a fixed position relative to each other, they do vibrate around their equilibrium positions due to thermal energy. This vibration occurs even in solids at absolute zero temperature, albeit at minimal levels. Thus, solid particles are not completely still.
Does solid iron have particles that move at 0 degrees c?
Yes, solid iron still contains particles that are in constant motion, even at 0 degrees Celsius. Although the motion is significantly reduced compared to higher temperatures, the particles still exhibit vibrational motion due to their thermal energy.
Is solvent a mixture component that did NOT dissolve to form the mixture?
The solvent is the substance in which the solute dissolves. The solvent does not itself dissolve because it is (usually) already a liquid. There are special cases. For example, it is possible for a gas to dissolve into a solid, in which case the solvent is a solid. Even then it is still true that the solvent does not itself dissolve. Only the solute dissolves.
What happens in a solid?
In a solid, particles are closely packed together in a regular structure, resulting in a fixed shape and volume. The particles still vibrate in place, but do not move past each other to change shape. Solids have a definite melting point.
What kind of solid holds it shape even though its particles do not have an orderly arrangement?
amorphous
Why does sound need a medium to travel through solid liquids and gases?
Sound is a pattern of vibrating particles of matter; these particles are necessarily in the form of a solid, liquid, or gas. If there are no particles of matter (in other words, a vacuum) then there will be no pattern of vibrations, since there is nothing to vibrate. Electromagnetic waves (such as light) are different. They are still generated by vibrating particles (usually electrons) but they do not consist of vibrating particles, but of electromagnetic fields. That is why they, unlike sound, can travel even in a vacuum.
Which organizes the phases of matter from the least particle motion to the greatest particle motion?
The phases of matter in order from least particle motion to greatest particle motion are: solid, liquid, gas, and plasma. In a solid, particles are tightly packed and vibrate in place. In a liquid, the particles are more free to move around but still relatively close together. In a gas, particles move freely and rapidly, while in a plasma, particles are highly energized and move even more rapidly.
What happens when a solid is cooled?
When a solid is cooled, the particles lose energy and move more slowly, causing them to come closer together. This decrease in energy leads to a decrease in the overall volume of the solid, resulting in contraction. If cooled further, the solid may reach its freezing point where its particles arrange themselves in an ordered structure, forming a crystalline solid.
Why are the particles in a solid in perpetual motion?
Particles in a solid are in perpetual motion because they possess kinetic energy due to their constant vibrations and oscillations. The particles may also have rotational and translational motion, even though they are closely packed together in a fixed position. This motion is a result of the thermal energy within the solid, which causes the particles to continuously move.
What phase has tightly packed particles?
The phase when the particles are most closely packed together is the solid form. liquid is farther apart, and gases are even farther.
Is a mattress a rectangular solid?
Yes even though it is 'bouncy', it is still a solid because it can not melt etc.
Which is true about particles that make up solid matter?
The same particles of matter that make up a solid are also the same particles of matter that make up a gas or a liquid. Basically matter consists of atoms. At the simplest level, the particles of atoms are electrons, protons and neutrons.
