What will most likely happen if a sound wave moves from the air through a solid? a. it will increase wavelength b. it will decrease in speed c. it will increase in speed d. it will decrease in wavelength

Answer is: c. it will increase in speed.

Sound waves travel faster in more dense material, and the more dense the material the louder the sound is.

Sound travels approximately fifteen times faster through the metal railway tracks than through air.

The speed of sound is faster in solid materials and slower in liquids or gases.

The denser is material, the closer are the molecules  to each other and the less time it takes to molecules to pass the sound to each other and sound is faster .

c. it will increase in speed is the correct answer.

Explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
