Answer:
The answer to your question is V2 = 5.09 l
Explanation:
Data
Volume 1 = V1 = 5.0 L
Temperature 1 = T1 = 5°C
Volume 2 = V2 = ?
Temperature 2 = T2 = 10°C
Formula (Charles law)
V1/T1 = V2/T2
-Solve for V2
V2 = V1T2 / T1
-Convert temperature to °K
T1 = 5 + 273 = 278°K
T2 = 10 + 273 = 283°K
-Substitution
V2 = (5)(283) / (278)
-Simplification
V2 = 1415 / 278
-Result
V2 = 5.09 l
So you can know if you have to pack up your belongings and moving somewhere else
Answer:
London dispersion force.
Explanation:
London dispersion forces act between all molecules whether they are polar or non-polar.
It's very simple... if we remember value of Universal Gas Constant R and Ideal Gas Law, so...
Ideal Gas Law
pV = nRT, where:
p - pressure (in kPa),
V - volume (in L),
n - number of moles (in mol),
R - universal cas constant (in kPa * L / mo l* K),
T - temperature (in K)
n = m/M, where:
n - number of moles,
m - mass (in grams),
M - molar mass of ingredient (in g/mol) - you find this at Periodic Table.
pV = nRT ---> pV = mRT/M ---> pVM = mRT ---> pVM/RT = m
p = 17615 kPa
T = 273.15 + 23 = 296.15 K
V = 43.8 L
R = 8.314 kPa * L / mol * K
M (for argon) = 39.948 g/mol
and
m = (17615 kPa * 48.3 L * 39.948 g/mol) / (296.15 K * 8.314 kPa * L / mol * K)
m = 13803.93 grams of Argon
