Answer:
Diagram 1
Explanation:
The solubility of the oxygen gas in water has to do with the interaction of the oxygen with the dipoles in water.
Water is a polar molecule having oxygen as the negative dipole and hydrogen as the positive dipole.
Water can interact with the oxygen atoms in the molecule via intermolecular hydrogen bonds with molecular oxygen as shown in diagram 1.
The answer for the following mention bellow.
- <u><em>Therefore the final temperature of the gas is 260 k</em></u>
Explanation:
Given:
Initial pressure () = 150.0 kPa
Final pressure () = 210.0 kPa
Initial volume () = 1.75 L
Final volume () = 1.30 L
Initial temperature () = -23°C = 250 k
To find:
Final temperature ()
We know;
According to the ideal gas equation;
P × V = n × R ×T
where;
P represents the pressure of the gas
V represents the volume of the gas
n represents the no of moles of the gas
R represents the universal gas constant
T represents the temperature of the gas
We know;
= constant
×
=
Where;
() represents the initial pressure of the gas
() represents the final pressure of the gas
() represents the initial volume of the gas
() represents the final volume of the gas
() represents the initial temperature of the gas
() represents the final temperature of the gas
So;
=
() =260 k
<u><em>Therefore the final temperature of the gas is 260 k</em></u>
