How does the solubility of a substance change with a rise in temperature?
With a rise of temperature, the solubility increases
What happens to the solubility of gases with the increase in temperature?
solubility generally increases with a temperature increase
When NaH is added to water the hydroxide concentration increases what can you include about NaOH?
The premise of this question is incorrect. When NaOH is added to water the hydroxide concentration increases. NaOH is a base. If a substance decreases hydroxide concentration it would be an acid.
What happens to the solubility of a solid in water as the temperature increases?
Although the solubility of most substances increases with temperature (eg you can dissolve more sugar in water when it is hot than you can in the same amount of water when it is cold) with gases the solubility decreases with temperature, so that cold water will hold more gas than the same amount of hot water. As oxygen is a gas its solubility decreases as the water temperature increases.
The solubility of nitrogen gas in water with increasing pressure and with increasing temperature?
increases, decreases
Why does speed of light increase after passing through water?
The speed of light depends on the electrical properties of whatever substance it's in. It has nothing to do with what substance it used to be in before, or what substance it's going into next. -- If it goes from air into vacuum, its speed increases. -- If it goes from air into water, its speed decreases. -- If it goes from water into air, its speed increases. -- If it goes from water into diamond or jello, its speed decreases.
What is acidity of substances?
Acid is a substance that, when added to water, dissociates (dissolves) to release H+ ions into the water. The higher percent of the acid that dissociates, the stronger the acid.
Do water in the hydrosphere increases or decreases over time?
It increases.
The density of sea water increases as?
the density of sea water increases as salinity increases and temperature decreases
When water freezes does it decreases in volume?
No. In fact it increases.
How does the solubility of a substance change with a rise in temperature?
With a rise of temperature, the solubility increases
In general the density of sea water increases as?
salinity increases and temperature decreases....
When water freezes its mass increases or decreases?
Neither
Why does density of water below 0 degree Celsius first decreases then increases?
First decreases then increases ... as what changes, exactly? The point of maximum density for liquid water occurs at 3.98 degrees Celsius. This is mainly due to some semi-complicated effects from hydrogen bonding, which is stronger in water than in nearly any other substance.
Can the size of the particles that the water can transport increases as the water velocity decreases?
no it does not
What happens to the solubility of gases with the increase in temperature?
solubility generally increases with a temperature increase
Does boiling water weigh more than cold water?
Actually it's not weight we are dealing with here, it is actually density. So what happens is when temperature increases, the density decreases and volume increases or vice versa if the temperature decreases, the density increases and the volume decreases.
