Answer:

No.

Explanation:

No, individual particles do not move with the wave, it only oscillates back and forth its mean position. The particles in the medium transfer its energy to their neighboring particles and in that way the energy moves in the form of wave. The particles only vibrates on its means position instead of moving from one place to another. So we can conclude that Individual particles do not move with the wave.

What is the volume of a gas if 0.182 moles of the gas is at 1.99 atm and 83.4oC?

Pie

$\text{Given that,}\\\\\text{Pressure,}~ P = 1.99~ \text{atm}\\ \\\text{No. of moles,}~ n = 0.182~ \text{mol.}\\\\\text{Temperature,}~ T = 83.4^{\circ}~ C = 356.4~K\\\\ \text{Molar gas constant,}~ R = 0.082~ \text{L}~ \text{atm}~ \text{mol}^{-1}~ \text{K}^{-1}\\\\\text{Volume,}~ V =?\\\\\text{We know that,}~\\\\~~~~~~~PV =nRT\\\\\implies V = \dfrac{nRT}{P}\\\\\\~~~~~~~~~~=\dfrac{0.182 \times0.082 \times 356.4 }{1.99}\\\\\\~~~~~~~~~~\approx 2.68~ \text{L.}\\\\\\$

$\text{Hence the volume of the gas is 2.68 L.}$

SEP Develop a Model: The element argon (Ar) has eight valence electrons and is a liquid at very low temperatures. Sketch a model

Flura [38]

Larger molecules experience larger dispersion forces due to more distance of valance of electrons from the nucleus.

<h2>Cause of stronger dispersion force
</h2>

Larger atoms and molecules have stronger dispersion forces than smaller atoms and molecules because in a larger atom or molecule, the valence electrons are present farther from the nuclei than in a smaller molecule.

They are less tightly held to the nuclear charge present in the nucleus and can easily form temporary dipoles so we can conclude that larger molecules experience larger dispersion forces due to more distance of valance of electrons from the nucleus.

Entropy measures _____. 1 point<br> A. Energy<br> B. Heat Transferred<br> C. Disorder<br> D. Force

dlinn [17]

Answer: Option (C) is the correct answer.

Explanation:

The degree of randomness or disorder is known as entropy. This means that more randomly or rapidly the molecules of a substance are moving in a container or in the Universe more will be its entropy.

For example, gases move more rapidly that solids or liquids and hence gases have high entropy.

Therefore, we can conclude that entropy measures disorder.
