As the temperature of a solvent increases, the solubility of any gas dissolved in that solvent decreases.
For example:
when the temperature of a river, lake or stream is raised high , due to discharge of hot water from some industrial process the solubility of the oxygen in the water is decreased .The fish and the other organisms that live in the water bodies such as rivers, ponds, lakes etc can survive only in the presence of oxygen and decrease in the concentration of the water due to increased temperature can lead to the death of the fish and this may in turn damage the ecosystem.
In the above example, water is considered as the solvent and the oxygen is considered as the solute. When the temperature of the solvent that is water increases, the solubility of the gas that is oxygen in the solvent decreases.
Therefore the answer is decreases.
Decreasing
Increasing
Explanation:
We can change gas to liquid by decreasing the temperature and increasing the pressure.
- Temperature is the degree of hotness or coldness of a body.
- It is a function of how much heat it has absorbed or lost.
- Heat causes the thermal energy of a system to increase and the particles becomes randomized.
- Pressure is the force per unit area of particles.
- If we decrease the temperature of gases, they have less kinetic energy and entropy reduces.
- The will not be random.
- Further increasing their pressure will bring them together and make them flow like liquid.
- This phase change is often called condensation.

Answer:
In 8 drops (0.20 mL) of the solution there is 0.0060 g of starch.
Explanation:
A 3.0% (w/v) is a weight/volume percentage that means that there are 3.0 g of solute (starch) per 100 mL of solution. Then, in 0.20 mL of solution:
I'm not sure but I think it is C. CrO3
Answer:
A. Solute
Explanation:
The solute is the material being dissolved.
Hope it helps! :)
