What Is The Most Likely Temperature Of The Water At The Bottom Of Lake Superior In The Winter?


What Is The Most Likely Temperature Of The Water At The Bottom Of Lake Superior In The Winter??

Explain why the most likely temperature of the water at the bottom of Lake Superior in the winter is 39.2 degrees F. Your explanation should include the role of hydrogen bonds between water molecules.

Which solution is likely to have a pH less than 7?

Question: A solution with a pH of 7 is neutral. A solution with a pH of less than 7 is acidic. A solution with a pH greater than 7 is basic.

Why are fall and spring temperatures colder in deeper areas of lakes than they are in the winter?

It would increase. Why are fall and spring temperatures colder in deeper areas of lakes than they are in the winter? Lake stratification causes colder water to sink in spring and fall.

Which of the following would have a pH of more than 7?

A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.
Most H+ ions: pH = 4 or pH = 5. Answer 4
Least OH ions: pH = 8 or pH = 9. Answer 8

When no more of a solute will dissolve in a solvent the solution is said to be saturated?

When the solution equilibrium point is reached and no more solute will dissolve the solution is said to be saturated. A saturated solution is a solution that contains the maximum amount of solute that is capable of being dissolved. At 20°C the maximum amount of NaCl that will dissolve in 100. g of water is 36.0 g.

When the pH of a solution is greater than 7 What is the solution?

At 25 °C solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are basic. Solutions with a pH of 7 at this temperature are neutral (e.g. pure water).

What type of solution has a pH greater than 7?

Basic solutions
The pH value of a solution directly measures the concentration of hydrogen ions (H+) in the solution. Acids have a large H+ concentration which translates to a small pH value. Bases have very little H+. Basic solutions have large pH values – greater than pH 7.Jul 21 2018

What temperature is lake water?

Water temperatures in lakes during summer months is not uniform from top to bottom. Three distinct layers develop: The top layer stays warm at around 65–75 degrees F (18.8–24.5 degrees C). The middle layer drops dramatically usually to 45–65 degrees F (7.4–18.8 degrees C).

Where is the warmest water in a lake?

The warm water species will seek out the warmest water they can which is often found at the bottom of the lake or pond. They will also stay away from areas with a strong current to save energy.

What determines lake water temperature?

It is related to the dissolved-oxygen concentration in water which is very important to all aquatic life. Many lakes experience a “turning” of its water layers when the seasons change. In summer the top of the lake becomes warmer than the lower layers.

Which pH is the most acidic?

The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above pure water has a pH value of 7.

Why does temperature increase in solvent?

If we heat the solvent the average kinetic energies of its molecules increases. Hence the solvent is able to dislodge more particles from the surface of the solute. Thus increasing the temperature increases the solubilities of substances.

Why increasing temperature of the solvent will speed up the dissolving process?

As the temperature of a solution is increased the average kinetic energy of the molecules that make up the solution also increases. … The increased vibration (kinetic energy) of the solute molecules causes them to be less able to hold together and thus they dissolve more readily.

Which is more soluble in water?

Among these given compounds sodium chloride is more soluble in water than potassium chloride. Because the solubility of a compound mainly depends upon the hydration energy and lattice energy. If the hydration energy of the compound is greater than lattice energy the solubility is more.

What is a pH greater than 7?

The range goes from 0 – 14 with 7 being neutral. pHs of less than 7 indicate acidity whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. … pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).

What has a pH greater than 7?

If a substance has a pH that is greater than 7 it is alkaline.

What is a pH level of 7?

The pH scale ranges from 0 to 14 with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).

Can the pH of an acid be greater than the pH of a base?

No acids can’t have pH greater than 7. By definition at 25 °C solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are basic.

How cold is Lake Superior at the bottom?

While the temperature of the surface of Lake Superior varies seasonally the temperature below 110 fathoms (660 ft 200 m) is an almost constant 39 °F (4 °C).

What is Lake Superior temperature?

Lake Superior is a town close to Great Lakes. August is the month with the highest water temperature at 65.1°F / 18.4°C.

Lake Superior Summary.
Description Value
Warmest Month Water Temperature: August with 65.1°F / 18.4°C
Wettest Month: December with 3.4in / 87mm

How cold is the bottom of Lake Superior?

The average depth of Superior is about 500 feet. It is the deepest (1 335 feet) of the Great Lakes. If you go swimming there in the hottest part of the summer you’ll soon learn that Lake Superior is also the coldest of the Great Lakes – brrr icy cold at an average temperature of 40° F (4°C).

Is it colder at the bottom of a lake?

The gravitational weight of all the water higher up in the lake presses down on the water deep in the lake. The pressure allows the water near the bottom of the lake to get cold without expanding and rising. Because of the pressure the water at the bottom of deep lakes can become cold without freezing to ice.

What is the hottest lake?

Death Valley in California has the highest undisputed temperature ever while New Zealand’s Frying Pan Lake is the hottest lake in the world with its acidic water reaching temperatures from 50 to 60C.

What month is lake water the warmest?


Well it depends upon the weather but the general rule is that the lake is slow to warm up in the spring (usually around July 4th where it is quite comfortable) and slow to cool off in the fall. Generally late August the lake is at its warmest assuming there has been hot weather in August.

Is water in a lake all the same temperature?

In small calm lakes water is usually warmer at the surface. In larger windy lakes and in rivers water gets mixed to deeper depths and they have more uniform temperatures.

What is the ideal temperature of water?

The best temperature for drinking water is room temperature (20°C / 68°F) for maximum flavour or chilled cold (6°C / 43°F) for maximum refreshment. However there are different types of water a myriad of reasons we drink it and varying personal preferences.

How cold is lake water in winter?

What happens under the ice of lakes? Water under the ice typically stays very cold but above freezing. Most lakes that form ice at the surface stay at about 4oC most of the winter months.

Where in the country is the water the most acidic?

The most acidic waters ever measured are percolating through an underground mine at Iron Mountain near the northern California town of Redding.

Which is most acidic among the following?

Hence among the given options p-nitrophenol is the most acidic.

What is the pH of pure water?


Pure water has a pH of 7 and is considered “neutral” because it has neither acidic nor basic qualities.

How does temperature affect solubility?

For many solids dissolved in liquid water the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

How does temperature affect the solubility of oxygen in water?

What Affects Oxygen Solubility? … First the solubility of oxygen decreases as temperature increases ¹. This means that warmer surface water requires less dissolved oxygen to reach 100% air saturation than does deeper cooler water.

Does solubility decrease with temperature?

Summary. The solubility of a solid in water increases with an increase in temperature. Gas solubility decreases as the temperature increases.

How does temperature affect the speed with which the solute dissolves?

Temperature. The temperature of the solvent is another factor that affects how fast a solute dissolves. Generally a solute dissolves faster in a warmer solvent than it does in a cooler solvent because particles have more energy of movement.
