I feel like it expresses time, but if there is another answer and they say otherwise, then they are probably right.
Hope this helps!
Given:
m = 0.240 kg = 240 g, the mass of O₂
V = 3.10 L = 3.10 x 10⁻³ m³, the volume
Because the molar mass of oxygen is 16, the number of moles of O₂ is
n = (240 g)/(2*16 g/mol) = 7.5 mol
As an ideal gas,
p*V = nRT
or
V = (nRT)/p
where R = 8.314 J/(mol-K)
When
p = 0.910 atm = (0.910 atm) * (101325Pa/atm) = 92205.75 Pa
T = 27 °C = (27 + 273) K = 300 K
then the volume is
![V= \frac{(7.5 \, mol)*(8.314 \, J/(mol-K))*(300 \, K)}{(92205.75 \, Pa)} =0.2029 \, m^{3}](https://tex.z-dn.net/?f=V%3D%20%5Cfrac%7B%287.5%20%5C%2C%20mol%29%2A%288.314%20%5C%2C%20J%2F%28mol-K%29%29%2A%28300%20%5C%2C%20K%29%7D%7B%2892205.75%20%5C%2C%20Pa%29%7D%20%3D0.2029%20%5C%2C%20m%5E%7B3%7D)
V = (0.2029 m³)*(10³ L/m³) = 202.9 L
Answer: 203 liters
It is simply called Entropy.
Answer:
decrease the height
Explanation:
height is directly proportional to the g.p.e
Choices 'a', 'c', and 'd' are true.
In choice 'b', I'm not sure what it means when it says that masses
are 'balanced'. To me, masses are only balanced when they're on
a see-saw, or on opposite ends of a rope that goes over a pulley.
Maybe the statement means that the mass of the nucleus and the
mass of the electron cloud are equal. This is way false. It takes
more than 1,800 electrons to make the mass of ONE proton or
neutron, and the most complex atom in nature only has 92 electrons
in it. So there's no way that the masses of the nucleus and the electrons
in one atom could ever be anywhere near equal.
