Protects, helps thermoregulate, provides sense of touch, helps remove waste
D. Is the answer because it has the greatest biodiversity
Answer:
Biodiversity is something I care about and I do appreciate the benefits it gives humans. I do wish everyone cared about it.
Answer:
d) 2v
Explanation:
Since, root mean square speed of a molecule,
![V_{rms}=\sqrt{\frac{3kT}{m}}](https://tex.z-dn.net/?f=V_%7Brms%7D%3D%5Csqrt%7B%5Cfrac%7B3kT%7D%7Bm%7D%7D)
Where,
k = Boltzmann constant,
T = temperature of gas,
m = mass of molecule,
Also, the temperature of a gas,
![T=\frac{pV}{nR}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7BpV%7D%7BnR%7D)
Where,
p = pressure of the gas,
V = volume,
n = number of moles of gas,
R = universal gas constant,
![\implies V_{rms}=\sqrt{\frac{3kpV}{mnR}}](https://tex.z-dn.net/?f=%5Cimplies%20V_%7Brms%7D%3D%5Csqrt%7B%5Cfrac%7B3kpV%7D%7BmnR%7D%7D)
If V = 2V and p = 2P
Then,
![V_{rms}=\sqrt{\frac{12kpV}{mnR}](https://tex.z-dn.net/?f=V_%7Brms%7D%3D%5Csqrt%7B%5Cfrac%7B12kpV%7D%7BmnR%7D)
![=2\sqrt{\frac{3kpV}{mnR}](https://tex.z-dn.net/?f=%3D2%5Csqrt%7B%5Cfrac%7B3kpV%7D%7BmnR%7D)
Hence, if rms speed of a gas molecule under initial conditions is v then rms speed of a molecule will be 2v
i.e. option d is correct.
