What phase do dust particles exist?
Dust particles are tiny particles of solid material.
Could the temperature of a material increases the average of its particles also increase?
If the temperature of a material increases, the average kinetic energy of its particles will increase.
How does removing heat from a material change the motion of it's particles?
the particles slow down. hope this helps! :)
How does a thermometer help when comparing the energies of particles?
A thermometer measures the amount of thermal energy a material has. This thermal energy is related to the vibrational and rotational energy the particles in the material have. By using the thermometer to measure the temperature of a material you are, in effect, measuring the amount of energy the particles of that material have.
The Big Bang is regarded as the expansion of?
A singularity, made of unimaginably dense material.
What causes elasticity?
compression or expansion of an elastic material causes elasticity.
What is an elastic force that squeezes or pushes the particles of a material together?
Compression
What is the difference between a tansverse wave and a longitudinal wave?
If the particles of the material medium vibrated in a perpendicular direction to the direction of propagation of the wave then it is said to be TRANSVERSE If the particles vibrate parallel to the direction of propagation then it will be longitudinal
In particles in the material move back and forth along the direction of wave motion?
The answer is a compressional wave (;
In what do the particles in the material move back and forth along the direction of wave motion?
compressional wave
Why is compression used on bridges?
From a strength of materials viewpoint, most if not all materials are stronger (and less likely to fracture) under compression (where, put simplistically, the forces are pushing the particles of the material together) than under tension (where, put simplistically, the forces are pulling the particles of the material apart). Bridge designers probably try to put as many structural members into compression, however, as far as I know, any design and especially a truss will result in tension at least at some point, and in bending (never just compression).
The portion of a sound wave where the particles of the medium are pressed together is called?
The region of compression is where all the particles of the medium are closer to each other than usual. In a sound wave that usually means that the pressure in that area of compression is slightly greater than the mean pressure of the material in which the sound wave is traveling.
Sound waves are what waves?
Sound waves are longitudinal waves, which transfer energy by compressing particles, which then apply pressure on the particles infront of them. The point at which the particles are compressed is known as the compression, whereas the point at which the particles are most spaced out is known as the rarefaction
Why does sound go faster in metal than in air?
Sound travels by compression waves: transmission of sound requires particles (atoms, molecules) of the medium to be compressed and rarefied. There are more particles of material in dense objects and so sound travels faster.
What happens when particles of a material move farther?
When particles of a material move farther apart, it explodes.
The state of matter liquid solid or gas which a material resists compression?
Solids resist better to compression.
What phase do dust particles exist?
Dust particles are tiny particles of solid material.
