The speed of sound at 20 oC in air is 343 m/s.

The speed of sound in helium at 20 oC is 927 m/s.

The speed of sound in natural gas  (methane) at 20 oC is 446 m/s.

Explanation:

  • The speed of sound depends upon the density and elasticity of gas.
  • The speed of sound is the distance which is traveled per unit time by a sound wave as it goes through an elastic medium.
  • The speed of sound in gas depends only on its temperature and composition.
  • Also the speed of sound refers to the speed of sound waves in air.
  • Air IS 343 m/s
  • Helium is 927 m/s.
  • Natural gas (methane) is 446 m/s.

Give reason why wood is solid?
VARVARA [1.3K]

Solid wood is a term most commonly used to distinguish between ordinary lumber and engineered wood, but it also refers to structures that do not have hollow spaces. Engineered wood products are manufactured by binding together wood strands, fibers, or veneers with adhesives to form a composite material.

Woof. Hope it helps!!! :) ....Reason*

1. What specifically are you looking for in the IR spectrum to determine if the reaction has given the desired product? 2. What
Umnica [9.8K]

Answer:

You are looking for expected peaks in absorption spectra founded on structure of desired product, respectively on bound in desired compound. Every bond absorb specific energy from radiation which wavelength match to IR spectrum of light. Result of energy absorption is vibration of bond and bonded atoms (if they are not too heavy).That absorbed energy is seen as a peak in absorption spectra. These peaks are specific for each bound so you need to find peaks that mach to bounds in your desired compound and in that matter you can identify your compound.

In nuclear magnetic resonance you are looking for  peaks specific for atoms in your desired compound (H or C atoms). When external magnetic field is applied, atom goes in higher energy state. When atoms goes "relaxing", it releasing energy that mach energy gap from relaxed end excited state. That energy is detected on nuclear magnetic resonance spectra and it depends on neighbor atom so you can determine the position of atoms and identify structure of desired compound.

For better results it is the best to combine these two methods.
