Which has more dissolved gases in it-hot water or cold water?
Cold water generally has more dissolved gases than hot water. This is because gases are more soluble in colder temperatures compared to warmer temperatures. When water is heated, its capacity to hold dissolved gases decreases.
How can sand be dissolved?
Sand cannot be dissolved in water as it is a nonpolar substance, while water is a polar solvent. However, sand can be dissolved in certain acids such as hydrofluoric acid or in molten metals at high temperatures.
What mixtures can be separated by crystallization?
Mixtures that have a solute that is more soluble at high temperatures and less soluble at low temperatures can be separated by crystallization. As the mixture cools, the solute will start to crystallize out of the solution, allowing it to be separated from the solvent. Examples include salt dissolved in water or sugar dissolved in water.
Where is dissolved oxygen likely to be lowest?
Dissolved oxygen is likely to be lowest in water bodies that are polluted, have high temperatures, low levels of vegetation, or are highly stratified. These conditions can reduce the amount of oxygen that can dissolve in the water, leading to lower levels of dissolved oxygen.
What changes the amount of dissolved oxygen in the water?
Factors such as temperature, pressure, salinity, and the presence of organisms can affect the amount of dissolved oxygen in water. For example, higher temperatures typically result in lower dissolved oxygen levels, while photosynthesis by aquatic plants can increase dissolved oxygen through oxygen production.
Why does it take 5 teaspoons to float an egg?
The five teaspoons of salt dissolved in the water increase the density of the water. Once the density of the water is greater than the density of the egg, the egg will float.
Which has more dissolved gases in it-hot water or cold water?
Cold water generally has more dissolved gases than hot water. This is because gases are more soluble in colder temperatures compared to warmer temperatures. When water is heated, its capacity to hold dissolved gases decreases.
How many teaspoons are in 8 grams?
Teaspoons are a unit of volume, grams are a unit of mass. You cannot convert them without more information.
Are the gases dissolved in the water during the day balanced?
No. It is not balanced it varies with the variation in temperatures.
How can sand be dissolved?
Sand cannot be dissolved in water as it is a nonpolar substance, while water is a polar solvent. However, sand can be dissolved in certain acids such as hydrofluoric acid or in molten metals at high temperatures.
How many teaspoons are in 85 m?
It depends what the medium is. 85 ml of water is 17 teaspoons. Other items will be different.
How many teaspoon of sugar dissolved completely in 20ml of water?
5.5 teaspons
What is the matter of seawater?
Sea water is water with a few thousand different dissolved salts and a variety of dissolved or suspended organic compounds.
What mixtures can be separated by crystallization?
