Answer:
lower
Explanation:
The higher the sea level, the lower the atmospheric pressure. This is due to the density of air decreasing as the altitude increases.
The relationship between pressure and solubility of the gas is given by Henry's law as:
where,
is the solubility of the gas.
is proportionality constant i.e. Henry's constant.
is pressure of the gas.
(given)
(given)
Substituting the values,
To convert 
to 
:
Molar mass of benzene, 
= 
Now for converting into 
:
Since, 
So, 
.
Hence, the solubility of benzene in water at 
in is 
.
Answer:
(1) breaking a pencil (2) rusting of iron
Explanation:
breaking a pencil does not alter the chemical properties of the pencil, it merely breaks it into 2 while the rusting of iron is changing the properties chemically because the iron is oxidizing and reacting with the water and oxygen in the atmosphere
