I believe the first blank is inertia
The fraction of gas phase molecules is calculated by the division of final pressure to the initial pressure.
Fraction =
(1)
Here, initial pressure = 1.0 atm
final pressure = ![1.0\times 10^{-10} torr](https://tex.z-dn.net/?f=1.0%5Ctimes%2010%5E%7B-10%7D%20torr)
First, convert torr into atm
1 atm = 760 torr
final pressure = ![\frac{1.0\times 10^{-10}}{760}](https://tex.z-dn.net/?f=%5Cfrac%7B1.0%5Ctimes%2010%5E%7B-10%7D%7D%7B760%7D)
= ![1.316\times 10^{-13}atm](https://tex.z-dn.net/?f=1.316%5Ctimes%2010%5E%7B-13%7Datm)
Now, put the value of initial and final pressure in formula (1)
Fraction =
=
Thus, fraction of the gas phase molecules =
![\simeq 1.3\times 10^{-13}](https://tex.z-dn.net/?f=%5Csimeq%201.3%5Ctimes%2010%5E%7B-13%7D)
It would be conduction since you car is made out of metal and almost everything in it is too so when you touch its very hot like it got conducted heat
Answer:
There are
number of molecules.
Explanation:
Given that,
Volume, V = 22.4 L
Temperature, T = 0°C = 273.15 K
Pressure, P = 1 atm = 1.013 bar
We need to find the number of molecules. Let there are n number of molecules. We know that, ideal gas law is as follows :
![PV=nRT\\\\n=\dfrac{PV}{RT}\\\\n=\dfrac{1.013\times 22.4}{0.08 314\times 273.15}](https://tex.z-dn.net/?f=PV%3DnRT%5C%5C%5C%5Cn%3D%5Cdfrac%7BPV%7D%7BRT%7D%5C%5C%5C%5Cn%3D%5Cdfrac%7B1.013%5Ctimes%2022.4%7D%7B0.08%20314%5Ctimes%20273.15%7D)
n = 0.999 moles
No. of molecules,
![N=n\times N_A\\\\=0.999\times 6.023\times 10^{23}\\\\N=6.01\times 10^{23}](https://tex.z-dn.net/?f=N%3Dn%5Ctimes%20N_A%5C%5C%5C%5C%3D0.999%5Ctimes%206.023%5Ctimes%2010%5E%7B23%7D%5C%5C%5C%5CN%3D6.01%5Ctimes%2010%5E%7B23%7D)
So, there are
number of molecules.
2 liters may be 1.5 to 1.9 rounded up to 2 or 2.1 or 2.4 rounded down to 2.
2 - 1.5 = 0.5
percent error = (absolute error / quantity) * 100
percent error = 0.5/2 * 100% = 0.25 * 100% = 25%
Choice C. 25%.
