QUESTION 1
Several factors influence the amount of gas that can dissolve in water. These factors
determine how easily gases such as oxygen or carbon dioxide dissolve in biological fluids.
1. Partial pressure of the gas
The amount of gas that dissolves in water increases as the partial pressure of the gas
increases. When the pressure of a gas above the liquid is higher, more gas molecules move
into the liquid until equilibrium is reached. Therefore, higher partial pressure leads to greater
gas dissolution.
2. Temperature of the liquid
Temperature has an inverse effect on the solubility of gases. As the temperature of the liquid
increases, the solubility of gases decreases. This happens because gas molecules move
more rapidly at higher temperatures and escape more easily from the liquid.

move more rapidly at higher temperatures and escape more easily from the liquid.
3. Surface area of contact
The larger the surface area between the gas and the liquid, the greater the amount of gas
that can dissolve. A larger surface area allows more gas molecules to come into contact
with the liquid at the same time, which increases the rate and amount of dissolution.
4. Nature or solubility of the gas
Different gases dissolve in water at different rates depending on their chemical properties.
Some gases, such as carbon dioxide, dissolve more easily because they react chemically
with water to form compounds like bicarbonate ions.
QUESTION 2
The skin plays an important role in respiration in certain animals. This process is known as
cutaneous respiration. In this type of respiration, gases such as oxygen and carbon
dioxide are exchanged directly through the skin.
