Children, even those that are vaccinated, may develop rotavirus disease more than once. That is because neither natural infection with rotavirus nor rotavirus vaccination provides full immunity (protection) from future infections. Usually a personâs first infection with rotavirus causes the most severe symptoms.
Because molecules move quicker at higher temperature, causing them to collides more. Since they collides more, reaction occurs to be a lot faster to. And that's why things dissolve quicker in hot water than in room temperature water.
1 Gases can dissolve in water. 2  The dissolving of a gas in water depends on the interaction between the molecules of the gas and the water molecules. 3  The amount of gas that can be dissolved in water depends on the temperature of the water.4  More gas can dissolve in cold water than in hot water.O2 is soluble because water molecules are attracted to these polar areas. The bond between carbon and oxygen is not as polar as the bond between hydrogen and oxygen, but it is polar enough that carbon dioxide can dissolve in water.
