Why do dead animals swell?
When animals die, their bodies start to decompose. This process involves the breakdown of tissues and the release of gases such as methane and hydrogen sulfide. These gases can cause the body to bloat or swell as they accumulate within the tissues and body cavities.
How would the fish in a lake be affected if large amounts of hot water from a power plant or factory were released into the lake?
When the temperature of water rises, the solubility of gases goes down. This causes the fish to not be able to breath well.
What is it that Plants and animals take in and then give off?
Plants take in carbon dioxide and give off oxygen through the process of photosynthesis. Animals take in oxygen and give off carbon dioxide through the process of respiration. This exchange of gases is essential for the survival of both plants and animals.
What animals live in the atmosphere?
No animals are known to live in the atmosphere, as it lacks the necessary resources to support life such as food, water, and shelter. The atmosphere is composed of gases and extends from Earth's surface up to outer space, making it inhospitable for animal life. Animals typically inhabit the lithosphere (land), hydrosphere (water), and biosphere (areas where life exists).
Why are different gases important to life?
Different gases play important roles in supporting life on Earth. For example, oxygen is essential for cellular respiration in plants and animals, carbon dioxide is used by plants for photosynthesis, and nitrogen is a key component of amino acids for protein synthesis. Without these gases, life as we know it would not be sustainable.
Which best explains the importance of dissolved gases in the ocean?
Dissolved gases in the ocean are crucial for supporting marine life. Oxygen, for example, is essential for the respiration of aquatic organisms. Gases like carbon dioxide also play a role in regulating pH levels in the ocean, impacting marine ecosystems. Overall, the balance of dissolved gases in the ocean is key for sustaining life in aquatic environments.
What happens to the solubility of oxygen in a pond as the pond decreases temperature?
As the pond decreases in temperature, the solubility of oxygen increases. This is because cold water can hold more dissolved gases than warm water. This can benefit aquatic organisms, as they rely on dissolved oxygen for survival.
The solubility of gases do what as temperature increases?
The solubility of gases decrease as temperature increases.
How with temperature changes solubility of gases?
The solubility of gases increase at low temperature.
What happens to the solubility of gases when temperature is increased?
Solubility of gases in liquids decreases with increase in temperature. When gases are dissolved in liquids, heat is evolved. Following Le Chatelier's principle, as the temperature increases, the solubility decreases. This is the reason that aquatic species are more comfortable in cold water as compared in warm water.
The primary function of external gills in aquatic animals is to do what?
The primary function of external gills in aquatic animals is to exchanges gases. However, gas exchange is more difficult with external gills.
What are the Physical and biological factors affecting the solubility of dissolved gases in aquatic ecosystems?
Physical factors affecting the solubility of dissolved gases in aquatic ecosystems include temperature (lower temperature increases gas solubility) and pressure (higher pressure increases gas solubility). Biological factors include photosynthesis (increases oxygen levels) and respiration (decreases oxygen levels), as well as microbial activity and nutrient levels that can influence gas solubility.
In gases solubility is inversely proportional to?
temperature. As temperature increases, the solubility of gases decreases. Conversely, as temperature decreases, the solubility of gases increases.
What are questions for aquatic chemistry?
How do pH levels impact aquatic ecosystems? What are the sources and impacts of nutrient pollution in aquatic environments? How does temperature affect the solubility of gases in water? What is the role of dissolved oxygen in supporting aquatic life? How do contaminants like heavy metals and pesticides affect water quality in aquatic systems?
How does pressure affect the solubility of gases?
At high pressure the solubility increase.
What happens to the solubility of gases as the temperature increase?
solubility generally increases with a temperature increase
Why does the solubility of gases increase in liquids on increassing the temperature?
Increasing the temperature of a liquid decreases the solubility of gases in that liquid. This is because higher temperatures disrupt the intermolecular forces between gas molecules and the liquid, allowing the gas molecules to escape into the atmosphere.
