Chapter 10: Problem 115

Explain why fish in a pond die if water becomes too warm.

Short Answer

Expert verified
Answer: Fish in a pond die when the water becomes too warm because the amount of dissolved oxygen in the water decreases, making it difficult for fish to obtain sufficient oxygen for their bodily functions and survival. Warmer water temperatures also lead to increased metabolic rates in fish, which requires more oxygen. This combination of low oxygen levels and increased oxygen demand can cause stress, suffocation, and eventually death to the fish.

Step by step solution

01

Understand the basic needs of fish

Fish, like all living organisms, require oxygen to survive. They primarily obtain oxygen from the water they live in by extracting dissolved oxygen through their gills. Oxygen is critical for various physiological processes, such as respiration, digestion, and maintaining metabolic rates.
02

Learn the relationship between water temperature and dissolved oxygen

The amount of dissolved oxygen in water is closely related to temperature. As water temperature increases, the amount of dissolved oxygen it can hold decreases. This is because warm water molecules have more available kinetic energy, which decreases the attraction between water molecules and oxygen. As a result, oxygen has a harder time dissolving into warmer water, and the overall amount of dissolved oxygen decreases.
03

Understand the impact of low dissolved oxygen on fish

Low dissolved oxygen levels can be harmful, or even lethal, to fish. When the amount of dissolved oxygen in the water decreases, fish must work harder to extract sufficient oxygen for their bodily functions. This places stress on their body and increases their vulnerability to disease, parasites, and other environmental threats. If oxygen levels drop too low, fish can become disoriented, sluggish, and ultimately die from suffocation.
04

Consider fish's metabolic rates in warmer water

A fish's metabolic rate increases with warmer water temperature. This means that the fish's body functions at a faster pace, requiring more energy and oxygen. Unfortunately, when water temperature rises, and dissolved oxygen levels decrease, fish may not be able to obtain the required amount of oxygen to support their increased metabolism, leading to stress and even death.
05

Explain fish death due to warmer water

In summary, when water in a pond becomes too warm, the amount of dissolved oxygen decreases, making it difficult for fish to obtain sufficient oxygen to support their bodily functions and survival. Moreover, their increased metabolic rate at higher temperatures exacerbates the problem as their oxygen demand increases. If the water temperature remains high and dissolved oxygen is not replenished, the fish in the pond can ultimately die from suffocation and the effects of physiological stress.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Fish Physiology
Fish physiology is fascinating because it determines how fish interact with their environment. Fish require oxygen to fuel their bodily functions, just like humans. They obtain this oxygen in a unique way - through their gills. Gills are specialized organs that extract dissolved oxygen from water during the fish's breathing process. When a fish takes in water through its mouth, it passes over the gills and oxygen diffuses into the bloodstream.
  • Gills have thin membranes to facilitate easy oxygen absorption.
  • Dissolved oxygen is essential for respiration, digestion, and energy metabolism.
If the oxygen levels in water decrease, fish struggle to meet their physiological needs, impacting their survival.
Water Temperature
Water temperature significantly influences the water's capacity to hold dissolved oxygen. Warm water is less capable of retaining oxygen compared to cold water. When water temperature rises, it energizes water molecules, causing them to move more and become less likely to bond with oxygen molecules.
  • Increased temperature = increased kinetic energy of molecules.
  • Less attraction between water and oxygen molecules means lower dissolved oxygen levels.
Therefore, as the temperature of a pond increases, the dissolved oxygen level decreases, making it challenging for fish to extract the necessary oxygen from the water.
Fish Metabolism
Fish metabolism refers to the chemical processes that occur within the fish's body to maintain life. Metabolic rates in fish are controlled by water temperature. As temperatures rise, fish metabolism speeds up, requiring more oxygen to support increased activity and energy use.
  • Faster metabolism demands more oxygen for energy production.
  • Warmer water can lead fish to "overheat" metabolically, depleting energy reserves quickly.
Sadly, when water becomes too warm, the decreased dissolved oxygen is inadequate to meet the higher oxygen demand from an increased metabolic rate, leading to stress and potentially fatal outcomes for the fish.

Liquid substances are often compared for their physical properties in different applications. Comparison of two liquids \(\mathrm{A}\) and \(\mathrm{B}\) at constant temperature and atmospheric pressure shows that liquid A has higher viscosity and surface tension, a higher boiling point, and lower vapor pressure than liquid B. Are these data all consistent with stronger intermolecular forces in liquid A than in liquid B?

Describe how the surface tension and viscosity of a liquid are affected by increasing temperature.

A chef observes bubbles while heating a pot of water to \(60^{\circ} \mathrm{C}\) to poach vegetables. What are the gases in the bubbles and where did they come from?

The solubility of air in water is approximately \(7.9 \times 10^{-4} \mathrm{M}\) at \(20^{\circ} \mathrm{C}\) and 1.0 atm. Calculate the Henry's law constant for air. Is the \(k_{\mathrm{H}}\) value of air approximately equal to the sum of the \(k_{\mathrm{H}}\) values for \(\mathrm{N}_{2}\) and \(\mathrm{O}_{2}\) because these two gases make up \(99 \%\) of the gases in air?

What is the difference between the terms miscible and insoluble?
