If the absolute temperature of a gas is doubled, what happens to the root‑mean‑square speed of the molecules? Nothing happens to the rms speed. The new rms speed is 4 times the original rms speed. The new rms speed is 2 times the original rms speed. The new rms speed is 1.414 times the original rms speed. The new rms speed is 1/2 the original rms speed.

If the absolute temperature of a gas is doubled ; ( D ) The new rms speed is 1.414 times the original rms speed

The r.m.s speed of molecules in a gas can be calculated using the formula below ;

$v = \sqrt{\frac{3RT}{M} }$

T = absolute temperature

R = gas constant

M = molar mass

Also ; The rms speed of gas molecules is directly proportional to $\sqrt{T}$

i.e. v ∝ √T ----- ( 1 )

Given that the absolute temperature ( T ) is doubled the new value of T = 2T

Back to equation ( 1 )

v = √2T = √2 * √T

= 1.414

Hence we can conclude that If the absolute temperature of a gas is doubled The new rms speed is 1.414 times the original rms speed.

Answer from: girlysimbelieve

The new rms speed is 1.414 times the original rms speed

Explanation:

The rms speed (root-mean-square speed) of the molecules in a gas can be found by using the formula:

$v=\sqrt{\frac{3RT}{M}}$

where

R is the gas constant

T is the absoolute temperature (in Kelvin) of the gas

M is the molar mass of the gas (the amount of mass per unit mole)

We can rewrite the equation as

$v\propto \sqrt{T}$ (1)

which means that the rms speed is proportional to the square root of the temperature.

In this problem, we are told that the absolute temperature of the gas is doubled, so the new temperature is

T'=2T

Therefore, according to eq(1), we find that the new rms speed will be:

$v\propto \sqrt{T'} = \sqrt{2T}=\sqrt{2} \sqrt{T}=\sqrt{2}v=1.414v$

So,

The new rms speed is 1.414 times the original rms speed

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic
