Why does sound travel fastest though a solid?
Because the molecules or atoms in a solid is closer bonded, and sound travel trough bonds, or more scientifically the action-reaction of the electrical force´s potential.
Why solids are better transmitter of sound?
Because the molecules are closer together.
What are the factors affecting mean free path?
Density: As gas density increases, the molecules become closer to each other. Therefore, they are more likely to run into each other, so the mean free path decreases.Increasing the number of molecules or decreasing the volume will cause density to increase. This will decrease the mean free path.Radius of molecule: Increasing the radius of the molecules will decrease the space between them, causing them to run into each other more. Therefore, mean free path decrease.Pressure, Temperature, and other factors that affect density can indirectly affect mean free path.
Why do sound waves travel faster in denser substances?
Molecules are packed closer together, hence electrons are also closer together and it is the electrons that do the transmitting!!!!
What happen when energy is removed from a liquid?
A liquid becomes a solid when heat is removed. The energy content decreases, and the speed of the particles decrease. When bonds form, heat energy is given off. This reaction is an exothermic reaction.
Can the removing of energy increase the volume of a substance because the molecules come closer together?
No. It can increase the volume in some cases, but not BECAUSE the molecules come closer together. If the molecules come closer together, the volume will DECREASE.
Is the pressure decrease or increase with altitude?
Pressure is due to the number of molecules hitting you or your instrument. As you go up in altitude, there are less molecules hitting you, i.e., the pressure decreases. The higher you go, you are getting thinner atmosphere, which means there are less molecules available, so the pressure is lower. Air molecules are more abundant closer to the surface, and therefore the molecules are closer together, i.e. higher pressure.
Why do you think more pressure on a gas causes the volume of the gas to decrease?
Increased pressure causes the gas molecules to come closer together, thus the volume also decreases.
Why gases highly compressible than solid?
In a gas, the molecules are free to move around and are relatively far apart from each other, so you can compress the gas and move the molecules closer to one another. In a solid, the molecules are already touching and so can't be moved any closer to each other.
When water molecules are moving closer together in the air is called?
When water molecules are moving closer together in the air it is called
As a planet approaches perihelion does it potential energy increase or decrease?
At perihelion, the planet is closer to the Sun, and moves faster, that means that the potential energy is at a minimum, and the kinetic energy at a maximum. The sum of kinetic + potential energy, of course, remains constant.At perihelion, the planet is closer to the Sun, and moves faster, that means that the potential energy is at a minimum, and the kinetic energy at a maximum.

Is there more pressure in the Sahara desert or at the top of Mount Everest?
There is more atmospheric pressure in the Sahara Desert. The number of air molecules around us decrease as we go higher into the atmosphere, which also causes the air pressure to decrease. Since the Sahara Desert is closer to sea level than Mount Everest is, there are more air molecules and more pressure there.
What is it When molecules of a gas draw closer together to become a liquid?
The process by which the molecules of a gas draw closer to become a liquid is called condensation
What are the differences of matter?
One of the differences that determines different states of matter from one another is the closeness of the molecules that make up the substance. Liquids are closer than gasses but solids are closer than liquids.
What is negative boosters used in traction?
negative boosters are used in the return path of traction system It is to decrease the voltage of the return path and to ensure that the return path voltage is much closer to ground potential
Are the molecules in your teeth closer together or farther apart than the molecules in your saliva?
The molecules in your teeth are closer together because your teeth is a solid and saliva is a liquid witch is farther apart (has more room)
Does volume in a solid increase or decrease?
Molecules in solids are closer together than liquids or gases so the volume generally decreases. Water is one exception to the rule. Water increases in volume by about 9% as it freezes.
