Oxygen concentrations of less than 3 ppm stress fish and are one of the leading causes of large "fish kills". Select all of the conditions below that could cause la levels of dissolved oxygen in bodies of water. O low pressure O high pressure O high temperature O low temperature O high viscosity
Ideal and Real Gases
Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,
Gas Laws
Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries were made by Charles, Gay-Lussac, Avogadro, and others. Eventually, these observations were combined to produce the ideal gas law.
Gaseous State
It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed forms of matter studied are solids, gases and liquids. The best example of a substance that is present in different states is water. It is solid ice, gaseous vapor or steam and liquid water depending on the temperature and pressure conditions. This is due to the difference in the intermolecular forces and distances. The occurrence of three different phases is due to the difference in the two major forces, the force which tends to tightly hold molecules i.e., forces of attraction and the disruptive forces obtained from the thermal energy of molecules.
![**Factors Affecting Dissolved Oxygen in Aquatic Environments**
**Oxygen concentrations of less than 3 ppm stress fish and are one of the leading causes of large "fish kills". Select all of the conditions below that could cause lower levels of dissolved oxygen in bodies of water:**
- [ ] Low pressure
- [ ] High pressure
- [ ] High temperature
- [ ] Low temperature
- [ ] High viscosity
**Explanation:**
This image presents a multiple-choice question aimed at identifying environmental conditions that can lead to lower levels of dissolved oxygen in aquatic environments, which can be detrimental to fish populations.
When selecting the conditions, consider the following:
1. **Low Pressure:** Typically, lower pressure can decrease the amount of dissolved oxygen because gases, in general, are less soluble in water at lower pressures.
2. **High Pressure:** High pressure can actually increase the solubility of gases in water, leading to higher levels of dissolved oxygen.
3. **High Temperature:** Higher temperatures generally decrease the solubility of oxygen in water, thus reducing dissolved oxygen levels.
4. **Low Temperature:** Lower temperatures increase the solubility of oxygen in water, leading to higher levels of dissolved oxygen.
5. **High Viscosity:** Increased water viscosity can affect the mixing and flow of water, potentially impacting oxygen levels, but this is less intuitive and may require further context for a definitive answer.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc25f84cd-37fe-4eda-bb3a-0db4abed4038%2F184d4214-f131-4a6f-9c71-0de3f1a6431a%2F9zqo87_processed.jpeg&w=3840&q=75)
