The density at 1,291 km from the surface of the planet is
[ (1,291 - planet's radius)/(planet's radius) ] ^ some power .
Answer:
Explanation:
Well, obviously a molecule with polar bonds can be polar in itself. It's like saying I am an atheltic person who can just reach the basketball rim with my head and also I can dunk.
But if the question is how can a molecule that in non-polar have polar bonds, well, its because the polar bonds' dipole cancels each other out. It's like a tight rope. If a person pulls in one direction, it intuitively, the rope would go in that direction. However, if a person pulls in the other direction with the same amount of force, the rope stays still. This is the same case. Although molecules can have different electronegativities, the pull of electrons in one direction is cancelled out by a pull in the opposite direction, making the net dipole 0.
This is common for main VSERP shaped molecules like linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral.

Explanation:
The given data is as follows.
n = 1 mol, 
Q = 1500 J, R = 8.314 J/mol k
(a) 
And, according to the first law of thermodynamics

And, in an isothermal process the change in internal energy of the gas is zero.
Hence, 0 = Q - W
or, W = Q
Expression for work done in an isothermal process is as follows.
W = 
As W = Q, Hence expression for Q will also be given as follows.
Q = 
Now,

[/tex]\Delta S = nR ln \frac{V_{f}}{V_{i}}[/tex]
= 
= nR ln 2
= 
= 5.76 J/K
Therefore, change in entropy is 5.76 J/K.
(b) As, Q = 
= 
= nRT ln 2
T = 
= 
= 260.4 K
Therefore, temperature of the gas is 260.4 K.
